Pretty fun! I liked getting lost in the maze and searching for the next snowflakes and keys.
Although I did feel like once I learned the layouts of the maps I could just B-line it for where I knew I needed to go next. Some sort of procedural generation for the levels would have taken this game to the next level (heh) for me. Also you have music in your credits, but I couldn't hear any in the game. Unsure if that's a bug or not.
