Really like the idea present here, a fun little game

Nice soundtrack, nice n-directional scrolling, etc. Good job on those mechanics. I don't like the built in type 'tutorial'. Just throw that on a title screen or something. Also, I couldn't figure out how the hell you shoot. Make this clear immediately after the game loads -- most players will simply move on if they don't get all the movement/fire nuts and bolts within ten or 15 seconds.

The graphics are nice, but the control scheme of having to be nearby the robot to launch it, plus it having only one level of launch force, makes it clunky.
