Shotgun in my Heart

Shotgun in my Heart is a micro Action RPG where you are in some sort of dungeon, fighting against monsters to get out. Armed with your trusty shotgun, which deals enough damage to one shot the creatures blocking your path, you must target their weak link to move to the next area. And if you miss… you will likely die. And another thing: each monster has two version, chosen at random (that made it pretty frustrating to go through, because you can only make one mistake…). Good luck escaping?

I ended up cheating to get to the end...
