It’s fun, it’s a game mechanic, but it’s an infinite game that ends up maybe lacking a purpose. Understandable, though, this it was made in about 3 hours!
If I were to improve on it, I would do less zombies spawning at once, maybe some more area to move around, and medipacks spawning in places every X seconds, so we would have health and would have to re-heal by getting the medicines.
