Very attractive game, tnx!
Btw it needs some fixes:
The continuos nag gun sfx forces to turn off the volume. Fix: just remove it (hearing enemies bullets only is mutch useful!).
Gamepad dead zone seems to be set at 2% (best 40% for XBox models) and buttons are in random position. My suggestion: Y to jump, B to shot, down key to duck. To shot down simply hold fire button and move down.
