I think it was an interesting concept. Unfortunately I think the game also seems too complex and requires too much reading to learn the rules. Normally I would be a bit more patient, but since it’s very hard to read, especially with the resolution restriction and the specific font that you used, it’s too big a barrier to fully enjoy the game.
The graphics is done well. I also like the palette swap and the (kinda) interactive main menu. The audio is ok.
After playing it for a while, there’s a lot of elements in the game I haven’t understood yet, like the purpose of the paint (which seems like an integral part of the mechanics). I mean there seems to be not much than cover the ground as much as you can. I unlocked the second color but I don’t know how it works. Like I said, it’s probably explained in the game but it’s way too hard to read, so maybe if nothing else you could add a tutorial in the game page for players.
