Loads of fun, uses the theme really well. My only complaint is that I feel the bullet obstacles don't really have a place in the game, since Lenny himself is already difficult to control.
Thank you :) I get your point, maybe I could replace them with some physic objects just to push a little bit the player but not damage him for it to be less punishing ? Not sure it would help since your complaint is about the hardness of controlling Lenny, but there may be something to do !
