Unsure of whether to put this here or on the gaming board, but I found a (really basic) paint program with a twist: it's inspired by roguelike games! This means the palette and brush shapes are procedurally generated and you cannot erase anything. You can export your drawing, but you can't save it. Basically, it's "a paint tool with permadeath".

I love challenges like these, so I thought I'd share
