This was originally designed in Unreal Engine 4 and needless to say it has been a lot easier to develop it on Stencyl.
I did try with Gamemaker in between but couldn't quite get my head around the GM Language and when I saw the post about the Stencyl Jam I became very aroused about the idea and decided to move the game over.
Arousal notwithstanding, the game is now on V0.2 and is awaiting your high scores.
Enjoy!
