Other than the controls scheme keep screwing the player over, which everyone has already mentioned. The character art are good but I hope the rest of the art are just placeholder, because I don't really like the Beijing smog background and the colors for everything else.
Ngl, action platformer is not my type of game at all so I can't say I even get passed the second level. Difficulty curve is just too high for anyone who isn't a die-hard platformer player.
