This is really, really good. Gameplay is really solid (although it can be hard to hit enemies at times), and the art style is really good overall. It definitely needs controls listed in the menu, I spent a good 2-3 minutes running around before I thought of checking the game page for controls, after that the gameplay was much better lol.
Other than that I just wish the entire game had the same sketchy art style as the main menu because I really like the way it looks and I think it fits the game idea really well.
