Things I really enjoyed:
The 3 hit combo attacking felt spot on! You can delay between attack, animation cancelling felt right.
I enjoyed the art direction / music / sound effects. (the hand drawn wiggle shader is nice touch, but it's practically screaming "add cell shading" to me haha. ). Also the impact hitting the trees was satisfying!
The fruit slicing and splatters looked great!
Things that could use some work:
Game needs a bit heavier impact on hits (camera shake, deeper base on the hit sounds, etc.). I want to feel like im really beating on those trees and rats. ;)
I know that you were short on time, but the game doesn't have much of a goal. Given the time constraints, maybe just count the number of rooms survived and post that when you die as a reason for players to come back to it. Or total fruits gathered - until you can implement your smoothie mechanic.
I definitely see potential, this was great work given your limited time!
