B100X - Auto Dungeon RPG approaches dungeon crawling from an unconventional direction, combining automatic battles with the kind of equipment management and character optimization normally associated with much more demanding RPGs. Developed and published by Nussygame, it is designed around the idea that meaningful progression does not necessarily require constant input. Instead of manually directing every attack, the player prepares a character, selects a destination, and allows the resulting build to prove itself against increasingly difficult enemies. The result is an RPG that can feel remarkably casual at first while gradually revealing a substantial amount of strategic depth. The story follows Holly, an apostle of God who ventures into the Eternal Cave with assistance from the player, who takes the role of a mysterious witness. Its fantasy setting describes an ancient period in which heaven belonged to God while demons controlled the earth, establishing a conflict that goes beyond a simple treasure-hunting expedition. Holly's mission is connected to sealing the dangerous cave, but the journey also raises larger questions concerning demons, divine intentions, humanity, and the …

B100X: Auto Dungeon RPG is a strange little RPG that takes most of the parts I normally expect to control and lets the game handle them automatically. I choose a dungeon and a floor, then my character Holly goes through the dungeon and fights everything without me controlling each attack. My job is mostly about preparing her properly, checking the equipment she finds and making sure her build is strong enough to survive deeper into the Eternal Cave. At first that sounds like it would remove most of the fun, but there is actually a lot more going on once I start getting into the equipment and crafting systems. The equipment system is easily the part I find most interesting. I am constantly picking up weapons, armour and other items, then deciding what is worth keeping and what can be turned into something better. The synthesis system gives me a lot of freedom because I can combine equipment instead of simply waiting for the next stronger item to drop. There are also different jobs and skills that let me build Holly in different ways. I like this because the combat itself is automatic, but the decisions I make before sending her into a dungeon can have a big effect on how far she ge…

As a Mobile to PC player, this game is very grindy and oftentimes tedious. For example, there is a late game thing called "Jinx" that can and WILL kill you, eating up your continues until that wallet comes out. I played it a lot back then, and I came back to it here thinking it was going to get better, but the pieces of a story (what story?) are translated like Ghost Stories, the game is grindier than half of the MMO's I've played (Farming simulator is less grindy), and the continues system is still in the game. For the love of god, if you want to play something like this just clock in to a 9-5 and you'll get the same experience. The worst part is that the dev CAN make good games, it's just that this game isn't one.

Free so yes, I obviously got bored of it after an hour and a half, but that is a lot longer than most games these days -_-

Equip and meld items to increase the power of you're waifu Does an awful job of communicating difficulty to the player - Every 10 floors seems to have a massive spike which will kill you if you don't grind. As a new player I died too many times and have to wait 24hrs to continue playing. Try something else instead!
