Ghouls Underground Steam CD Key

A gigantic Shoot-em-up/metroidvania.
Only one level but this one is really gigantic to explore!
This is not an endless game, because there is an end, but it will take you so many hours to overcome it.
Lead a team of heroes to destroy evil in a dangerous labyrinth full of various enemies and traps. A lot of treasures and weapons to find!
Keyboard or usb xbox controller available (I don't try other joypads)
Warning this is not a simply shoot em up but a metroidvania too, so you need to find specific items to open specific ways.
