Absolutely Wow. I was a little bored at first and died alot collecting the keys but then the timer ended and I found myself in a top down shooter Doom style game and absolutely loved it.

Improvements
-Potions spawns outside of walkable terrain when close to the walls
-Found the platformer harder (Died10 times ) than the Top down shooter (Died once)
