A game called Limbus Company by Project Moon. It’s a gotcha game, so be warned, but imo, the good part is the story mode, not the ultra late game content, which is easily beatable without ever having to buy anything, wait for energy to recharge, etc. The best part is that unless you’re going for a super specific bleed, burn, poison build, the default characters are literally better than the ultra rare drops. So yeah, it’s free and imo is worth checking out if you like the art, because it’s very pretty :)
