Thanks for the name inspiration Zay.
Do any of them have an irritating loud buzzing sound? I was getting that but I think it was just Audacity/my speakers. If not I'll have to... something.
Lab Level collection (with imaginary level/plot design!)
Neuron - Just runnin' through some corridors filled with blinking lights and test rooms, smashin' bad guys and dodgin' lasers.
Reactor - Getting closer to the center of the lab. Pipes and power conduits, large consoles, more dangerous enemies.
Core - Oh no! Looks like they grabbed your buddy and turned him into a half-machine monster and put him in front of the self-destruct button!
Critical (NOT FINISHED) - Well, you pressed the button. You should probably get out, if those alarms are of any importance. Timed stage because I'm evil.
