cool game, funny monsters and sfx. I love the monsters models and the speed of the arm when firing is amusing.
the lives counter is not that clear even if the screen darkens.
too bad the tutorial frames are partially hidden (by the door or your arm) maybe try to place them on the left to be more visible at any time. and the door which is not that important on the right ;)
found a bug where if you stay afk and loose all your lives you can still play afterward and score indefinitely.
