I love this! The art style and the blinky snowball are so cute! The inertia of the big ball vs the jumpiness of the small ball are so intuitive. That being said, when I'm an big inert snowball pacing back and forth ever more sluggishly, hoping to amass enough snow to double jump, it can get tedious. It might come later in the game (I couldn't get much far) but I think some levels would benefit from slopes, planned falls down curves that the player has to time before restarting the level to try again (sort of like a Sonic the Hedgehog type of level where you launch youself). I think the horizontality of the game doesn't give the concept enough of a playground. Still very nicely rounded and original, I had fun!
