I had fun with this. Gameplay would benefit with a change in controls. Move with wasd and shoot by clicking with the angle the mouse pointer relative to the character. As it is now it was difficult to target enemies in uneven height platforms.
Thanks for your rating. We tried to do that at first, but with GameMaker it was very difficult to implement so we tried to do the shooting with the keyboard instead. I agree that it's a bit clunky but I'm glad you still had fun with our game anyway!
