The author (Nikolai Delhaize) is looking for people to submit pictures drawn in the paint program.
"for my thesis book i thought it would be cool to have a collection of scribbles and doodles made by users online testing the app, so i released the prototype rom of painter on my website"

This Kickstarter marks the very first two physical NES games making use of gbdk-nes - the NES backend of gbdk-2020 which powers a good deal of the BB Studio engine.

These two puzzle games will have a physical space on my shelf... as well as a fuzzy feeling inside.

#gbdk-2020 #nesdev #retrogaming
Tomorrow (March 7) at 1 PM EST, @dalyengames.bsky.social will be launching the kickstarter campaign for all of these games... thanks for making it happen! Stayed tuned.

GB Studio is an amazing tool for making real Game Boy games.

But what if Big Brother NES wants to play too?

Now there's BB Studio - a hacked version of GB Studio, to run your GBS games on the GB's Big Brother!

NOW YOU'RE PLAYING WITH WALL POWER.
