Very polish game!
Cute and nice pixel art. Loved the explosions and the snow particles.
The physics were a bit "floating" in the beginning, but the game give us the option to improve it when level up. Very cool. I felt the player's hit boxes a little strange: sometimes I could swear that I correctly stepped on the enemy but the game gives me damage (adding a hit stop when damaged helps the player know whats hit them).
Overall, really a great entry and very fun game! Congrats
