Mining, but with a Shotgun

You are a miner stuck in a cave and these gross zombie-ghost hybrids are coming to kill you. Kill them instead to survive for as long as you can. They sort of explode when they die, so rocks fall everywhere. Make sure you keep clearing them out. Pick up that gooey stuff dropped from rocks to enhance your bullets and do mega damage!

P.S. - I would love some feedback on my game. This game is complete and I won't really be updating it, but I'd still like to know what I did right and wrong so I can further improve my game design skills. So please leave a comment. And thanks for playing!
