Some of the game mechanics are a little bit broken and the Bollie AI can be really annoying and a bit broken sometimes (but it can be disabled easily).
However the art, simple but still just challenging enough "quests", and peaceful atmosphere of the game definitely make up for any trouble I had. It sometimes makes you think, but it doesn't stress you out if you can't figure something out.
Definitely worth $3 (probably more than that IMO) so I definitely recommend it even though it's a short game.
