The art looks good and the gameplay is good except for when there aren't any enemy it just feels like a mining simulator with a timer until you are randomly shot from an enemy outside the camera. I think the weapon you are using should be highlighted or something in the ui to better see what you are using. I like how you made the enemys follow the player, but not too much by stopping the enemy when he is inside the camera. When shooting the enemys i think it there should be an animation when he dies rather than just removing them. Other than that the menu was nice and it was really fun and easy to understand.
