Ascent Alpha

Ascent is a new FPS game, combining elements of some of my favorite classics. It is currently in Alpha. Almost all features are developed and the Beta should be ready in a couple of months. I am looking for suggestions for control schemes. Comments are welcome. Any and all suggestions will be considered. This is a test application in infancy with updates every few weeks. Instructions: Lower left joystick controls left/right direction and forward/reverse movement. Two buttons above the joystick rotate clockwise / counter-clockwise. Upper right set of buttons control up/down direction (center two buttons) and fire energy blobs(left button) and gives a speed boost (right button).
