I get that this was a demo or something, or that it wasn't finished, but man that was broken as all hell. Literally you could fire at a rate so fast it makes machine guns seem archaic. This causes enemies to be obliterated the second they show up, and all power ups quickly become yours. Even the difficulty you chose at the start doesn't make any real difference as you quickly shoot at hundreds of bullets a second. Needless to say, this wasn't that good, and I hope the next one improved on this.
