This game is so much fun! I love the music, it made the game seem so much better. You should make a version 2 with differnt stuff like new upgrades such as turrets, missles and other cool crap. Oh ya, I found a way to cheat. If the guns runs out right click and your mouse will show and when you click an enemy they explode even though you didn't shoot a beam. Ther is also two glitches one where the gun upgrade doesn't do anything and the save button sometimes doesn't work. I was at level 30 or 40 or something like that and I saved it but when I came back later I was at 20.
