I really like the upgrade system here but I think it really needs to have the controls more like DvM (talking about locking the gun into one direction). And badges of course!
Scrolling through the comments I see the average IQ of the Kongregate user isn't that high... The game was ok I had fun playing it and I would definitely play the sequel if there is one.
To the people who say that binds are horrible I don't get it just use the Keys to move and w to jump seems to be working out pretty good for me.(or the other way around whatever works for you)
