Great execution for the theme. Love the whole art style and sound design, It worked perfectly!
I think With the difficulty curve the first level is absolutely the most difficult. It took me a few attempts to do it but when I moved on the game didn't feel like it was getting any more difficult so I breezed through the other two levels.
Nothing is more satisfying than dropping a giant hammer on chickens! I think you could even add more feedback like a pop when it hits
Overall it's very fun and even more impressive considering the time frame.
