This is a very fun and addictive game! The visuals and sound effects are great and really sell the impact of hitting an enemy.
I think it’s a little too hard to control. The main issue being it’s hard to aim the fist at enemies since when enlarged it changes it’s angular speed. And the fact that when enlarged it drags the player behind it, which means you bump into an enemy you’ve just hit if you are not careful.
I think with how punished you are for getting hit it’s important to keep movement controls as precise as possible. Or alternatively you could make getting hit a little more tolerable by spawning heals from enemies from time to time.
Overall, it’s an impressive entry!
