Wire up your robot pals using sensors and logic gates to solve the puzzles and maybe even reunite with an old friend.

The original development thread is here.

I've put it up on itch.io as well.

Here's a silly thing that came out of another thread where I was contemplating parsing game content out of strings, and just how far to take the idea. Eventually configuration/data formats always end up becoming programming languages (heck that's how Lua got its start), so why not just make it a full programming language from the start? Get a jump on Greenspun's 10th rule.

So, I implemented lisp-8, a small lisp dialect intended to be used in pico-8 carts. The core code is about 1400 tokens after some fairly aggressive (ugly) optimizations. I could cut it down by about 200 tokens if pico-8 ever exposed Lua's _G variable.

And of course, once you've got a scripting language embedded in your game, why not allow your players to type in code and make a full programming game out of it?

Of course, it might take a week to type in your program with the limited input available on pico-8. So if you don't want to type in code yourself, hit tab to cycle through some sample lisp statements.

This editor cartridge is, of course, itself implemented in lisp-8. It's all in the first _init function at the top of the code, the rest of the file is the lisp-8 engine.

Ultimately I don't know if this has any practical use at all, and it sure is slow, but it's kind of fun. It gave me lots of good ideas about how I can better compile together my assets for my actual pico-8 programming puzzle game, at least.

I loved these old "programming" puzzle games in the Apple II era, like Rocky's Boots and Robot Odyssey. I thought it seemed like a good fit to do something similar for pico-8, since unlike most programming games we don't need full keyboard input, we can get by with just two buttons.

I know this is a small thing, but I often forget to quit pico-8 and I leave it running in the background overnight, which prevents my Mac from sleeping. Maybe it could be tweaked so that pico-8 only blocks the display from turning off/computer from sleeping when it's in run mode?

I tracked it down to pico-8 by running pmset -g assertions which showed:

   pid 164(coreaudiod): [0x001a40d7000197e9] 11:05:27 PreventUserIdleSystemSleep named:
    Created for PID: 93582.

PID 93582 is pico-8. So it appears it's because it's keeping the audio channel open.

I was thinking the other day about how the remote lakes in the mountains near my house are stocked with fish by dropping them out of planes and helicopters. What a strange experience that must be for a fish! So I decided to make a little game about it.

So far there's no real goal, you just fly each fish into the lake and stock it up with happy, swimming fishes. I haven't decided yet whether I'll add a more concrete goal or keep it as is. Not totally happy with the helicopter sprite yet, either.

My entry for the Weekly Hour Game Jam, week 1 2017. The theme was "Happy New Year", so I created a fireworks show. To add a bit of interactivity, you can move a cursor around and draw shapes with X or Y to create different firework effects.

I definitely still had a few things on my TODO list after an hour, so it's missing some polish, but overall I'm happy with what I finished in 60 minutes.

For my first PICO-8 project I decided to make a game similar to Pac-Man Battle Royale, my favorite multiplayer arcade game of the decade. Right now you can play 1-player with an AI opponent, or 2-player battle.

The basic pac-man gameplay is there, but so far the only mechanic I've implemented is players bumping off each other on collision. I still need to add a lot more gameplay and flair, and hopefully find some ways to make it my own (besides the greek labyrinth theme). This is my first PICO-8 project, I'd welcome any feedback!
