(its M from MCAS)
Cool game, better than most of the stuff I've made, which isn't a lot to be honest. I like the touch of the bullets giving knock back.
The only thing I have a problem with is the reset level function. Sometimes I'd be in a game then I press the space bar by accident which made me lose my progress :( . Maybe if you mapped it so a further key like ENTER or P, then it would be easier.
I really don't have a lot of things to say about the game, its simple like that.
