That's a juicy one! Congrats mate. I just think it's a bit too hard, it could start slower and have some kind of weapon upgrades while keeping the same one shot idea. Also, the spawning can be a bit frustrating sometimes because the border of the playing area is too risky to be at since the player can't know if there will be an enemy spawning there or no, some sort of visual showing that a enemy will spawn at that location could be a good option. Overall, very cool entry, congrats
