Solid sokoban game! It does need an undo button, but the puzzles were short and simple enough to where it wasn't *too* frustrating to finish them. I think the ants blocking the path of the blocks is also a bit of a tough one, on one hand it does add a bit of nuance but on the other hand it created a few soft-lock scenarios in my playthrough that forced some unnecessary resets. I'd like it if pushing tiles over an ant would squish them, instead of getting blocked.
