I am pretty confused about the game works. How do you get ammo? I picked up a ton of stuff but I seemed to randomly actually get any ammo. I picked up tons of shotgun shells for example but I would actively pick up some and my ammo wouldn't go up. Other than that I like the concept of a tower defense where you actively fight as well! I would have liked to see a more unique idea than Plants vs Zombies though. Definitely give this game some polish!
