Hi! Heres my experience, hope it helps!
Just played some of your game, its very well made. I like the intro. I got past the first gate (got stuck for a bit, didnt know to pull the trigger) wasted a lot of ammo shooting the wood trying to break it, then got past the soul door. The only power ups i seemed to be getting were radiation x5 and skull x2. Neither i new how to pick up. i stood in them, shot them, thought i clicked on them, but i might have missed because there were zombies everywhere. bought a flare , but it fell through the basket and onto the ground where i couldnt pick it up. the ground was several inches below my floor. then i got attacked from behind, got to scared and had to back out lol.
Great work!
