This game got a decent pixel graphic.
The music is nice. a chilly lofi piano sounds great, but it doesn't loop though
The gameplay revolve around taking advantage of the ability difference between your size.
This can create an interesting puzzle if the game is longer.
One of the blockage for player is the second stage where you're supposed to wall jump off the edge of the wall because there's absolutely no clue you can do that. (I only know from comments)
I'm not sure why you don't use same the sign to you used to tell the player everything else but not this particular part.
The third stage, you have to jump across pole, the difficulty curve is vertical here.
Due to the fact that the that you have to precisely throw a snowball, and one miss meant reset
and also how the camera would make it difficult to see the ground you're going to land.
But the checkpoint is near enough that it is not too frustrating.
It is fun though.
