Go towards your left, there is a weapon there for you to fight with, press space to shoot and use your curser to aim. That is all I am gonna tell you since you've gotta experience things yourself and learn how to play without just reading. There is a high score for both Kills and Time, let's see if you can beat my high score, have fun!
This took me about 15 hours, I worked on this for 5 hours for 3 days strait so uh yeah, this was fun to make and was not that hard to make to be honest, but I have more projects coming up and they are good, I've been working on one for a while now and it may not be release for about a year now.
