This game is pretty tough, but once I got the hang of timing the punch to hit enemies I quite enjoyed it. I like how there are several levels, each complete with a boss battle. It reminds me more of an NES game than a Nokia one to be honest, but that's not necessarily a bad thing.
Unfortunately I couldn't complete it because the second boss's charge attack seems completely unavoidable. I can jump over it once but always get hit on the way back.
