Laboratory Labyrinth

You've been sent to retrieve several vials containing a substance of potential importance to the development of science in an abandoned research facility, however you find that it has been overrun by several mutants. Navigate your way around the maze to locate these vials and find the exit. Watch out for mutants and avoid touching the acid spills.

I would like to acknowledge the following for their help, wouldn't have done this without them:
@spriters-resource.com/
- for some of their sprites that I used.
@danPost
- for his transparency adder program that I used to trim off the excess edging from my sprites
