Okay game, I had some fun with it. Although, I don't see how it relates to the theme of "use it or lose it" exactly. Also, having left mouse to attack in a game that isn't otherwise mouse controlled seems pretty questionable.
Thank you! I ran out of time sadly and was unable to add as many levels as I want, I was going to use some levels to kinda lead you into losing some actions before the next level which would make you use the provided power up that would inverse your control when activated so if you lost move left, you'd have to inverse controls so when you clicked right it'd move you left. I can see what you mean about the mouse. Thank you for the feedback!
