Use mouse to steer player, arrows or WASD to move space to shoot. WATCH OUT FOR ZOMBIES! Also you can just walk through heals to use them. Use E to collect Materials and V to place wood, B to place brick and N to place metal. Special energy regenerates if used. Use Q to activate Deadly Wormhole.
I used one tutorial to make basic stuff like gun and zombie random but all else is trial and error from me. I got building inspiration from my favourite games Minecraft and Fortnite.
