It all starts out quiet but as your go in it quickly gets in action. fight your way through hidden enimies, claustrophobic walls, boobie traps, friends, and destroying the boss through a river of acid. You get the red key when you defeat him. When you go through where you need to you will get your next message. Haven't you recalled seeing a red door before? UPDATE! Sorry everyone! I forgot that one of the vortex's was blocked off and you couldn't finish the game. Well it's fixed now and the game is now possible to finish. Enjoy!
