That's impressive you made local co-op for your game! I agree with pretty much everything Scoot said before, the characters and the buildings look nice. I like the rolling animation for the snow monsters, and that pixel lighting too. I think some timings could be improved to make the game feel nicer, like the enemy projectiles could hang in the air longer while you are close to them, and I'd love for the player's forward momentum to be preserved while landing after a jump. Something like a block or dodge action could be fun too!
