the jump doesn't work
the mouse can go out-of-bounds on windowed mode
the zombies can get too close and instakill the player
not sure if you didn't need these, they wern't in the list
1. There is no jump but the keybind remains.
2. Play fullscreen lol. (Don't worry I'll fix it. :/)
3. What? If you mean instakill by getting gang raped by 10+ zombies then yeah.
If you get experienced in Unity, you should turn this into an actual game project, possibly with co-op, like L4D.
Not sure if co-op will be possible. Code is written in a very sloppy manner that there would be a lot of issues. I guess I could do it but as a separate game.
