The hero is doing his daily jogging routine until misfortune happens and he ends up in abandoned mines. He tries to figure out the path to get out of there and the game idea is just about that get out of the place, defeat bosses along the way and collecting skills and stuff.
As a classic Metroid fan this immediately catched my eye. However, without an Xbox360 controller I would have dropped the game again immediately. The default control scheme for the controller is okay, but for the keyboard it's simply confusing. I know what you tried to achieve (essentially mapping the 4 colored buttons to the cursor keys), however this is more confusing than helpful. Why not use cursor keys for movement, space for jumping and control for shooting? Other small things I noticed: You die too fast, even at the beginning. Also having limited ammo and obviously no way to shoot while jumping (plus delays after jumping or ducking) makes the game far more harder than it should be. Other than that... nice animations and interesting ideas (e.g. snakes running around blocks), so might grab it later on, but for now it's too cumbersome to play for my taste.
PS: How about changing graphic options so you have to hit an apply button first after changing something and then you having to confirm the changed settings once they applied? That way you'd also eliminate crashing issues making the game unplayable.
