Unnecessary, fun systems.
Graphics are stored not as an array of pixel colours, but pixel indices to a "skin" graphic. Allows just this skin to be updated and all animations reflect the new colours. Also left/right asymmetry can be kept no matter flip direction! #indiedev #gamedev #picotron #pico8

This week in untitled stealth ninja platformer. Improvements to light/shadow, some camera work and player animations. Next I guess some kind of gameplay maybe? Games have that right?

Slowly progressing on a stealth platformer. Recently added foundation for lights and player field of view.

Judging game difficulty is hard when you're the dev playing your game countless times during development.
That is why play testing is so important! Lesson learnt!

Samurise now updated with less frustrating levels (I hope)!

I recorded a play through of my #pico8 game Samurise!

My best run yet, but one very annoying death prevented me from finally getting the No Deaths achievement! 😭

Playing with #picotron colour tables.

Next game a light and shadow based 2D ninja stealth platformer along the same vein as Mark of the Ninja?

I've had many wonderful comments in the couple of days since release, it makes me very happy to know that even a small handful of people got enjoyment and pleasure from my game.

Thanks to everyone who liked or commented and especially to those that played! <3
What a wonderful community.

My newly released free game Samurise looks great on the #powkiddy #rgb30 !

Of course it also works great on desktop or mobile direct from the browser over at @itch.io

Please give it a play if you are into this kind of thing!

I've gotten pretty good at my game during development but still never managed to complete the no deaths achievement!

Old release, but not posted on here, so...

Sonic 16x16
#sonicthehedgehog in 16x16 pixels made in #pico8!

Play here
itch: troypicol.itch.io/sonic16x16
pico8 bbs: www.lexaloffle.com/bbs/?tid=44632

Finishing/releasing stuff is hard even when it's tiny like this so I'm proud of it despite its flaws!

Love the sound of #pico8 tunes.
Always end up leaving music until the last minute! #chiptune

Cool #pico8 feature used in my game. The screen can be split vertically into two separate palettes. I use this feature to give different levels completely different feel/colours.
Here you can see a good example when I was working on it of the same level split into two palettes. #gamedev #indiedev

Expanding my 2024 #pico1k jam entry into a full game. Runner/platformer with a few enemies for good measure. #pico8 #indiedev
