Hey! This is my first Pico-8 game, a clone of the DS game Polarium.

It contains 100 levels. You can get a hint for every level if you're stuck.

There's also a level editor, which lets you create your own custom levels. You can even share levels with other people with 30-digit passwords. These passwords are completely compatible with Polarium, so you can also find lots of levels other people have made online for an extra challenge. 20 custom levels can be stored.

:: Bugs

I've already had a few bug reports:

  • Movement doesn't work on mobile. I changed how I detect direction to disallow diagonal movement, which seems to work great on PC and web, but not on mobile for some reason. Any input welcome. The way I do it now is probably dumb. Seems to be fixed, but let me know if there are problems. Movement seems to act differently in the mobile player; for example, moving diagonally on mobile seems to move in a "staircase" movement now, while on PC/web nothing happens.
  • Completing levels that are multiples of 10 does not update the completion status Fixed
  • Completing a stroke that does not flip any tiles (ie. it only covers the gray border) does not correctly reach a win/fail state (must use the pause menu to return to level select) Fixed

This is pretty cool, I don't really remember the original very well so I can't say how it compares, but it seems well put together, congrats.

Awesome work!

Took me a second to figure out what I was doing on level 1. Once I got to level 13, it seemed impossible. Up until that point, the levels were all solvable by making the entire board a single color.

I Googled some Polarium gameplay and watched how horizontal lines were cleared instead of the entire board.

Anyways, it may help to have an early easy/small puzzle that cannot be solved by making the board a single color. Something like:

X0X
0X0
X0X

Which can be solved by a single vertical line.

Anyways, looking at the instructions, I see that they're pretty clear on this point :) I just didn't parse it on my first read through.

Suggestion:

  • After completing a level, increment the selected level to the next incomplete one (I kept navigating back to the level I had just completed)

Thanks for the suggestions!

The game is pretty close to the original, and most of the levels are from that game too. I'm trying to make some levels of my own, but I wanted to upload the game now and making 100 (or some large number) of good levels takes time, hehe. That would probably mean I should invalidate the save though.

I'll at least swap out one of the early easy levels with one that can't be solved with one color!

I'm not sure if automatically moving the cursor to the next incomplete level will be confusing or not, especially if someone has completed many of the inbetween levels, but I'll think about it.

I'll at least add the level number to the playing screen so you know where you are at all times, and also an indicator saying if it's already completed or not. Some cues like that would probably be nice.

@trevorade Thanks again for the suggestions, I've now implemented all of them in some way. Changelog:

  • Level 4 has been replaced by a checkerboard patterned level
  • The current level number is displayed while playing, as well as whether you have already completed the level
  • After completing a level, you can choose between going back to level select (which does not increment the selected level) and going directly to the next unsolved level. This seemed like a compromise that wouldn't confuse anyone. I just kept it simple: It will only go forward, not backwards. So if you have completed all subsequent levels, it will only let you go back to level select, even if you have an incomplete earlier level. I assume this functionality has introduced new bugs.

I like the changes!

Have you thought about music and sound effects?

P#52101 2018-04-28 09:33

::

Yes, but I've never made sound before. If I put music in it'll be the original's weird electronica I think.

P#52107 2018-04-28 13:51

Is level 100 posible?

P#52617 2018-05-11 12:27

:: Level 100 hint

@Chodot: Yes. Here's a pretty big hint, this is how the cleared level looks like (what lines should be black and which should be white):

I love Polarium. I completed the GBA version over 4 months a few years ago. Just an amazing game. The GBA version was in development first, then the developer Mitchell Corp took a break to make the DS version as a launch title for that system, afterwards returning to finish off the GBA version. The extra time spent on the GBA version shows as its a much better and more complete game IMHO. And it can be played one handed whilst commuting!

This is a really nice version. Well done!

I have a few thoughts:

  1. I find it hard to differentiate between the yellow and orange outlines. Maybe they could be more two more contrasting colours?
  2. After completion it should give you a secondary challenge, where you have to solve it "perfectly" using a set number of steps and/or starting and ending on designated tiles.
  3. The menu screen animation would be more useful if it showed the core concept of the gameplay: flipping paths of tiles.

@matt Thanks! I love Polarium too. I didn't know that piece of Polarium history! I always wondered why the first game came out for DS, and the sequel came out for the earlier GBA. I always thought it was because of the Game Boy Micro. I've actually been making a Polarium demake for Game Boy for a while, since that seemed the logical next step after GBA! This PICO-8 game was kind of a way to mock up stuff quickly for the Game Boy version.

  1. I'll think about that, thanks. The yellow is probably not easy to see on top of white tiles either, now that I've stared at it for a while.
  2. That's a good idea. I'm actually currently implementing a level editor, which is compatible with the original DS game (ie. you can use passwords to play custom levels from the DS game in Picolarium and vice versa), and the original game stores starting and ending tiles in the password (it knows them because you have to solve the level to save it). I was planning on using that information for a hint system like in the DS game, but I guess hints aren't really needed for the small 8x8 levels in this game. I'll finish up the level editor and then see if I can repurpose the start/end hints as a secondary challenge akin to Polarium Advance instead (the DS passwords don't store number of steps). Or, I guess, make Picolarium Advance, haha.
  3. That's true, I really picked it just to emulate Polarium's title screen. And mostly because it looks nifty. And I could use the fizzlefade algorithm. I even used it for the background on the itch page: http://tobiasvl.itch.io/picolarium

Thanks for the feedback!

Edit: Hmm, now that I think about it, I don't have enough cartdata to store whether or not a secondary challenge has been solved unless I shave off the number of custom levels you can save. Currently you can just save 20. That should be fine though, I still have room for 19 (or an even 18 to make the level select pretty).

Maybe now is the time to optimise level data storage? :)

P#52972 2018-05-23 19:54

::

Haha, yeah, I have already done that. I had to do it a while ago to save tokens. I now store them in the same representation as the passwords are generated from. I just haven't put up a new version here yet because it's not polished (although it's playable), but it's here: https://github.com/tobiasvl/picolarium/commit/4ade4725518169c42d5f61c3bb44d25b889a5579

Note that the hard coded levels in that commit are just 9 bytes because they don't have starting and ending squares yet, but custom levels in cartdata do have those, so they're 11 bytes plus a checksum byte.

Buuuut I don't need to actually store the checksum of each custom level in the cartdata, I could just calculate it every time it's needed for a password. That way I could store 19 custom levels sequentially, and then split up the 20th level into separate bytes and spread it over the checksum bytes of the other levels. Or store the levels as 11 bytes each sequentially, of course, but then it's a little harder to store and read them.

Thanks for being my rubber duck ;)

Great!

:: Picolarium 1.0

Big update:

  • Level editor, which lets you create your own levels.
  • Password system, which lets you share your custom levels with others, or import other people's levels. The passwords are compatible with Polarium for DS, so you can probably find lots of cool levels online. (20 custom levels can be stored.)
  • You can now get a hint (start and end positions) for every level in the pause menu. (@Chodot)

@matt: I decided to use the start and end positions as hints instead of secondary challenges. The levels aren't necessarily made to be solved in more than one (interesting) way anyway. I'll keep it in mind for a possible (GBA-inspired) sequel though!
