I loved the art and colors a lot in this game!
I figured the X button after noticing there must be something to help me get past the snowmen if jumping would not help me deal with them :D . I enjoyed the portrait mode of the game, I imagine it would work nice on mobiles!
It was a really interesting mechanic to have the snowballs recharge after a while and it made me strategize how I would spend them! Would be awesome to have the difficulty increase over time as well!
Would be cool to play this game again after an update with more visibility on obstacles and a small tutorial on keybindings/controls for new players :D
