Like the gameboy aesthetics, would of been nice if it had any sound. I found the control setup awkward. There's no point in having the mouse LMB used for attack when everything else is done via the keyboard. Especially when you have a/s for movement and space for jump. Made certain jumps awkward to do, resulting in you to use both hands on the keyboard. You could have solved this a number of ways, like using RMB for jump, W for jump, or, putting the attack button on the keyboard near space so as to have both hands on the keyboard. I think if you improve the controls, add some additional polish -- like sound to assist with game feel -- and this would make a nice demo or portfolio piece.
