While the graphics are not yours, it was arranged in an appealing way.
That being said, experimenting with what will appear in each season was a bit difficult endeavor, but still satisfying. What I'd maybe do is check whether the snowman would be stuck in walls before the switch and then simply prevent it. There were times where I got stuck in the wall during winter to recover my HP, and the screen was shaking uncontrollably because of the collisions. So, preventing the switch if there's no space would help with that.
But other than that I really liked the game.
