I had a couple hours of fun with this
Beyond the obvious (climbing animation, board-removing animation), some suggestions:
- hitboxes seem to be way off when they're climbing, clear headshots either miss or register as body shots
- I wanted a place to buy pistol ammo
- ground could use some more variation
- at one point, five zombies got stuck in the outer fence corner. I was wondering why nothing was happening, and a new wave wasn't coming either - the five remaining ones were all stuck outside

- related to above, tried to kill them with a grenade, but it disappeared outside
- the center trees are clearly made of two parts, when a bit farther you can see a horizontal line
- looking forward to being able to enter the buildings, etc
Relaying feedback from a friend:
- the time between waves is too long
- could use some small interactivity, like being able to shoot the car lights
- a way to change the resolution, more graphics settings in general
