Nice concept
I agree with some of the other reviewers that the controls may be a bit off but nothing you can't learn. When holding up your guy keeps jumping so only tap it to jump. When climbing a wall let him climb on his own you don't need to hold up, when you get to the top you won't jump in to a ninja. As for the last guy being impossible just wait until he stops swinging and get him lol took 2 sec to beat.
I love the concept of this, I wish there were more levels. Also it would be nice if there were more than just lanterns and gongs to interact with to finish the levels. It had good style nice animation it just wasn't to deep. Good time killer!
I looked forward to a sequel(so you should make one HINT HINT)
