Hey ! In your game, nice vibe you have :yoda: :)
I just wanted to point out some issues:
- The mouse is not lock to the game (fullscreen and window mode) so when I move around and the mouse exit the game window I can't clic to shoot without unfocus from the game.
- Maybe the player is walking a bit to slow. Make it faster and more reactive (same for the mouse sensibility, it should be more sensible)
A part from that nice game, I loved the laser gun and the sound ! I would try it again with some adjustments :p
