Wow. PICO-8 is extremely fun to work with, and I'm so happy I stuck around to learn how to use it!
Right now I'm learning how to work with tables and 'objects' to sort of port a game I'm currently developing called HellHole. It's a top-down shooter where you choose between controlling your body or the bullet (which is your soul).
So far, I've managed to not slow down the game with a shit ton of instances and that makes me happy!
I'll leave you with a gif of the latest bit of progress: A spawner, soul particles, and screen-shake.

The function peek4() does not properly check its number of arguments, so calling it with no arguments will cost zero cycles. Combined with any other function that costs fewer cycles than its number of arguments, such as shl(), this can be exploited to reclaim CPU cycles.
Here is a function that reclaims n cycles:
function reclaim(n)
for i=0,n/5 do
shl(peek4(),peek4())shl(peek4(),peek4())
shl(peek4(),peek4())shl(peek4(),peek4())
shl(peek4(),peek4())shl(peek4(),peek4())
end
end
|
I do not know to what extent this can be exploited, but here is an example.
The following program runs at 15 FPS:
function _draw() for y=0,127 do m=3+rnd() for x=0,127 do pset(x,y,(x+7)*m%5) end end print(stat(7).." fps",1,1,7) end |
But this one runs at 30 FPS:
function _draw() for y=0,127 do m=3+rnd() for x=0,127 do pset(x,y,(x+7)*m%5) end reclaim(200) end print(stat(7).." fps",1,1,7) end |

106 frames of animation, compressed and embedded in the cart (half in the code, half in the gfx segment).

To play follow the instructions and press the shown direction faster than your opponent. Use "x" to confirm and "c" to go back in menu.
For ethical reasons a vegan mode is included and can be activated via the settings.
(However we promise in our production and testing phase no animals were harmed.)
Feel free to comment and write us critics etc, as we are still learning and this is our first project.

I have started measuring function costs precisely, because I like accurate things. It’s all on the wiki but not fully complete.
Here are a few funny things I already learned:
- <code>x^.5</code> costs 16 cycles, whereas <code>sqrt(x)</code> costs 27
- <code>x^4</code> costs 8 cycles, but <code>x*x*x*x</code> only costs 3
Some of these, such as clipped <code>circ()</code>, are pretty tricky to measure, I hope someone can help!
Edit: removed claim about shl() because that function behaves a bit differently.

8 DAYS | RANDOM GENERATED GAME TITLE | PICO 8
Confusing Prison Mansion and what we did with the title.
This prison is so boring. I mean what are you supposed to do with all this free time.
Read books? No… and the interior as well. It‘s so lame. Could do with some color and nice new furniture.
To be honest I‘d rather be in a mansion right now.
Collecting keys, opening doors and stepping on that mysterious light spot might help with that.
Oh, and don’t get caught by the cop!
Confusing Prison Mansion is a challenging puzzle adventure created by three tired Students. For the first ever game we created, we had the challenge of using a random game title. We generated our game title with The Video Game Name GeneratorThe Video Game Name Generator.
Hope you enjoy our game.

This is a 'pretty unusual' Zombie-Shooter made by two students in less than two weeks!
In this game you are not the muscular Rambo-kind-of-guy - no...you are a Little baby who is shooting zombie babies!
So pull your diapers up, load your gun and be ready for the 'Baby Zombie Apocalypse'

Imagine you are a tough crusader living the medieval life. A great dragon attacks the castle and instead of just attacking the dragon and saving many lifes, the princess decides that it is more important that you save her holy cheese collection. Of course you follow her wish, because it is her, the beautiful princess, Britney, who you want to impress all your life.
So grab your loyal sword and shield and face the massive dragon... to collect the cheese bit by bit!

This is an indiegame that has been created within less than two weeks as a school project. These two weeks were very nerve-racking but we also enjoyed it.
Hopefully you will enjoy the game as well.
INSTRUCTIONS:
You only need your mouse for this game!
First of all you'll need to build the empire with the help of cute bunnies.
For this use the button on the top left of the button.
After a certain number of clicks, another button directly below and a button called 'duke' appears.
The duke that costs clicks for you.
That's how it works.
Have fun and do not forget to leave us your opinion below the comments.
Please consider that this game is still in progress.

This is the prototype we created in in school as our very first development project.
You control your fighter Johnny McJohnnson by hitting the directions on your keyboard.
In menu press "x" to confirm. I know pretty complex.
For any suggestions, critics or questions about my personal relationships and any existencial questions feel free to comment.

You play a cute deer-like girl within a forest, awaiting to catch the many fruits the magical tree has to offer, but be aware of the rotten fruits that rain down as well. You wouldn't like to go home with fruits that smell badly, would you?
How to play:
Move around with your left and right arrow keys and catch as many fruits as possible, only the good ones though.
If 'Y' doesn't work, use either 'C' or 'Z'.
Rotten Apple (Brown Fruit) = Avoid those, they give you -100 pts and -1 HP
Cherry = +50 pts
Orange = +20 pts
Apple = +10 pts
Peach = +1 HP
Your lifes (3 in total) are shown on the top right in the form of an either full or empty basket, all depending on your current life.

You entered an ancient jungle fortress which is filled with tasty bananas. Monkeyheaven some would think. But watch out! There's something lurking inside the darkness, protecting the bananas. Try to collect all bananas and extract them out of the fortress door.
