Got the beginnings of a game here. You need to make it pause on start though, I wasn’t even done reading the instructions before the first enemy had come over and punched me to death.
There was also something weird going on with the mouse capture. At first I couldn’t aim with the gun, but the mouse was locked so I couldn’t do anything. I needed to restart. Then esc unlocked the mouse OK.
Lots of action in this one.
