This is Nongünz, it's a really cool roguelike.
You go into a dungeon, find items augment your stats, weapons, skulls that give your abilities. You can make your own minions with skeleton parts who will go scavenge for you. You can free worshipers from cages who will give you points passively. There's this shrine in the middle where you can spend points to get guns and skulls.
The ost and visuals are great.
It's very cryptic, there's no text apart from the name of your minions and worshipers.
It was on steam and was removed, but soon there's gonna be a rerelease with a bit more content on several platforms.
