2/10
possibly has potential but who knows, your to do list :
1. fix the falling through the floor bug on the coin level (and probably others, didn't try to)
2. add something to make it interesting (not insulting the game, but as is, most people probably would be too bored to play beyond the tutorial)
3. make the tutorial skipable
4. consider animating the snowman differently when it walks/slides/whatever you call it, the bobbling left and right like he's floating in the ocean looks really lame and sorta half assed.
5. (up to you, since noone has any clue what game mechanics are to be added so maybe it's on your list already) either let the snowman sprint or roll or something to move faster even if only temporary.
i won't lie, this doesn't look like a good start, prove me wrong.
