Simple, but somewhat fun. I found that the game kind of lacks something; it feels very disconnected. The controls are very slippery and I feel like it would improve the game a lot to tighten up the main controls. The music is interesting, and the slightly variable sound effect of charging up and throwing a punch is nice, however, breaking things feels ultimately unsatisfying; as if there's no reaction at all. Crates just fall apart and most other objects simply disappear. A lot of this could be helped with particles or some added 'Explosion Force' applied to the rigidbodies that drop when you destroy a crate; or perhaps a sound effect when you actually strike an object. Overall, still fun and entertaining.
