Boss-Slaying Roguelike Game [Core Keeper]

Platform: Steam (PC) Price: $21,500 KRW (approx. $16 USD) Multiplayer available (up to 8 players) This game begins with the protagonist and their companions searching for a certain rock. The protagonist loses memory of the others and falls into a mysterious space. They must survive underground. It's a game where you mine ores by digging, smelt them to craft equipment, build up your stats, find boss rooms, and defeat various bosses. I found out that the protagonist was apparently thrown into this underground world by some kind of creature. The objective of this game is to defeat all 6 bosses present in the world. There are 3 bosses located inside the walls and 3 outside, and their locations are randomized depending on the seed. There's a ton of content. Besides mining and boss fights, there's also farming, raising livestock, exploring ruins, and much more. It took me about 130 hours to finish the game, which is apparently not even that slow. I recommend playing with a veteran friend. There's no tutorial, so if you don't have someone to teach you, the difficulty is high.
