COD Black Ops Zombies Like

This is a game I made a while ago for a school project but I have spent some more time on it during the summer break and its kinda finished now, by finished I mean I have everything I wanted and it looks pretty good. Of course its going to be buggy and full of problems but It can be fun to play! Thank you for playing!

How to play?

Gameplay is pretty simple, there are waves of zombies and they get harder and harder the more you advance, you gain money buy killing zombies and surviving waves. You can buy weapons with your money, you can pick up stuff like Ammo, HP and grenades. The game consists of 5 waves because I didn't want it to get really boring.

Controls?

Movement - WASD

Jump - Space

Throw Grenade - G

Use Heal - X

Change weapons - Numbers 1 to 9

Interact - E

ESC - Pause menu

Thank you for playing this game! Feedback is really appreciated! :)
