Visually this game looks incredible, I really like the look of the game.
Sadly even with a decent computer, this was a struggle to run without noticeable frame drops. Sadly with 3D games, you have to take every precaution to optimize your models as much as possible, I am curious how many builds in the background used precious rendering time and resources that could have been better spent in making sure the game ran as smooth and playable as possible.
I could maybe suggest since 90% of the time the gameplay was not with me looking at the building but the zombies and so you could probably swap the buildings out for a much simpler mesh that doesn't contain as many vertices.
The aiming was okay but it was hard to tell with the frame drops.
Visually I can say this game would be something I would love to play and what I did play had a lot of potentials, I think it's enjoyable but needs a great deal of optimization.
Sadly I am unsure if you knew what the limitation was but the game should not have contained any text whatsoever. Other than that I think this has potential!
