So good mate!

It actually doesn't persist by default. You must have added 'poke(0x5f2e, 1)' somewhere. This is the line that persists the palette. Just remove it, it isn't needed to change the palette or use the secret colours.

I'm basically never busy and yet the last two picotachi have been on days I am busy! Poor luck. Maybe next time

I'm definitely going to try and attend.

Secret palette almost a necessity! I wouldn't say "moved" to picotron, but I'm currently working on a project in it. I'll likely jump between the two depending on what I fancy working on at the time!

Yeah! My original intention using it was to have blood splatter on the character for example.

grim.ninja @grim.ninja · 21/07/2025
In theory yes! In practice generating the animation data referencing the skin pixels is time consuming and tricky enough even for a single character. But yeah certainly possible depending on the designs, especially for smaller and simpler characters.

grim.ninja @grim.ninja · 21/07/2025
Yeah the thinner platforms don't block the light.

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? #indiedev #picotron #pico8

Looks great mate. As somebody also developing a game on picotron I'd be really interested in your dev process and steam release process if you have any devlogs or blog posts!

grim.ninja @grim.ninja · 04/07/2025
I linked the manual entry, but basically just include the extra files in the export command.

Ah yeah that's a lua out of memory error. Most likely because you deleted a function body and caused some issue with parens8 parsing or something.
110
grim.ninja @grim.ninja · 03/07/2025
Hi, do you mean out of tokens/bytes when exporting? Or out of memory lua message when running? If the former, I know I was pretty close to the pico8 limits by the end so adding anything without taking away something else might be very tricky.

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

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)! 🎮 grimninjagames.itch.io/samurise 🎮 🎮 www.newgrounds.com/portal/view/... 🎮

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! 😭 www.youtube.com/watch?v=yOGe...

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 really like the aesthetic you've got going on here.

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. #pico8

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