For a one-person 48h jam, that's a cool little puzzle game ! The concept is not really original, but it had some little elements I didn't see in other similar games, like ice, that made me think differently.
The monsters are cute, but I must say that the sound when they move make my head hurt ^^'. I don't know if it's the volume, or just the sound itself (maybe both), but it was hard for me to focus with it ^^'.
Overall, I enjoyed playing your game ! Keep up the good work !
