Hello, I played your game! It was very fun. I did 2 runs, both reaching about 4 minutes. I like the fact that you can only shoot in the shadows. I didn't really put much attention into the upgrades. I figure the idea was having to decide which enemies you want to kill, but for the most part you could just kill all of them, that's what I did. Tbh I don't see that as a problem because it was fun just watching groups of zombies explode. Something that could be improved upon is more feedback when the player gets hit, since I didn't really notice sometimes. Overall, great game!
