Art of the game looks very good. Inverted mouse look made it impossible for me to play. There's no introduction, menu, presantation, game starts right away and gets back to the main menu right after you die. There's not even a you lose screen. You could respawn the player after death.
Good job on the art. Besides that, it's very rough game which is extremely difficult to play in it's current state. Don't lose your motivation and keep working on it. There's still a good basis for a game here. Good luck!
