Alright. That frozen ice lake background though took my breath away! If you look closely maybe you can see it was rushed but wow it made the game feel infinite. Really liked the theme and the ambient music fitted perfectly.
Suggestion: The tile grid really didn't match. I would have had the artist make big blocks of terrain that you could manually place around and you could script them to work the same.
Bugs: I fell through the floor into the grid once which meant my progress was lost. Level 3 didn't seem winnable? Had to taskmanager quit.
