Pretty fun concept and I like the designs of the insects and background, the game felt very creepy and got scarier as enemies showed up out of the background. I guess a couple of suggestions I have would be to show how many bullets you have for the gun as I couldn't shoot sometimes(assumed that was the reason and not a bug), and I guess the plane on which infected as shooting in their direction doesn't guarantee a hit and also increase the hitbox for physical attacks as the monsters get too close and then most of the time trying to hit them is just the screen shaking. I really like the concept though, gives me hollow knight with guns vibe (tone-wise).
