I really liked this game, played it all the way through. Level 9 in particular was quite tough! Other than level 9 being harder than 10, progression felt solid. Really liked the puzzle mechanic, especially when you added in the thicker ice.
Felt like the wizard didn't really look too wizard-like. I get that the top is a hood, but a more typical pointy wizards hat might have been more clear on the scale you're working with. Also could have done some robe bottoms.
Could really use some simple sound effects and music.
