Very fun game, but very short, and as lots of other comments say, there is a lot of potential. Some fruits with new mechanics could be cool, and maybe some unique lines, like diagonals that could get cursed. There could also be harder meta mechanics, like hub puzzles if there are worlds, and edge cases, like what if two objects are on the same tile. There could also be more stage items (I don't know what they're called), like portals.
I hope there's a new version, but if there isn't, that's also fine. :)
