This gem surfaces soon
We have it ready, but it is not unsealed yet. Come back when it opens.
Opens on 2026-07-24 (JST)
A hero who died an unfortunate death is granted mercy and a second life, sent into a dungeon that reshuffles itself with every attempt, and every battle from there on plays out on its own, no commands required.
A roguelike, auto-battle, NES-style retro RPG made and self-published solo by MSBgamedev (rendered as MSBgamadev in Steam's own developer field, a one-letter discrepancy from the same name used on the developer's own X account and in Steam community posts), who has stated directly on X, 'I am a Japanese indie game developer,' alongside a Japanese flag emoji. Per Steam's own listing, a protagonist who died an unfortunate death is granted mercy in the heavenly realm and a chance at a new life, then descends into a dungeon that reshuffles with every attempt; battles are fully automatic, with characters thinking for themselves and choosing their own best moves. Growth comes through 'Jewels' dropped by monsters or bought in shops, Armor Gems for defense, Weapon Gems for attack, and Skill Gems that determine which abilities a character's class can use, layered with a Chain system that raises damage on consecutive hits and a Chain Burst that upgrades magic attacks landed mid-chain. Each ending is reachable in roughly 2 to 3 hours, with optional difficulty-boosting items and secret bosses for players who want more, and an original chiptune soundtrack of over 20 tracks by Aomo Akane styled after late-1980s NES music. Released at ¥920, it is Positive at about 93 percent over 27 reviews (25 positive, 2 negative), a paid title, not free, fully launched and not in Early Access, with no AI-generated assets, and per Steam's own content descriptors, nothing sexual. It supports Japanese only, with an English localization still in progress and no confirmed date beyond the developer's own plan to time it to a Steam Auto Battler RPG Fest event; of its 27 reviews, 26 are in Japanese and not one is in English. A dedicated check of Siliconera, Kotaku, PC Gamer, and AUTOMATON's Japanese edition turned up no coverage of this game or its creator at all.

01First, the one feeling
- Per Steam's own text, characters think for themselves and choose their own best move, so the tension shifts entirely away from input timing and onto the build you handed them before the fight started, every Jewel a decision you made in advance and now have to trust.
- The Chain and Chain Burst systems reward attacks landing close together, so a fully automatic battle still has a rhythm worth watching for, the quiet satisfaction of seeing a party you built actually click into that rhythm on its own.
- This is a hero granted a second life after an unfortunate death, and knowing the developer built an entire progression system, not just a story beat, around getting another chance turns every dungeon that reshuffles itself into less of a punishment and more of another try worth taking.
02Who this is for (and who it is not)
For you
- You want an auto-battle roguelike RPG where the strategy lives entirely in party composition and gem builds, not in real-time input
- You want a genuinely solo Japanese production, self-published with no external publisher, from a developer who says so directly
- You want a Positive title (about 93 percent over 27 reviews) that Western game media has never once covered: not one of its reviews is in English
Not for you
- You want a large, statistically settled review base; 27 reviews is thin enough that a couple of outlier reviews would move the percentage, and this pick says so plainly
- You want direct command over combat; every fight here plays out automatically once it starts, with your choices made beforehand through gems and party setup

Journey of Reincarnation Buried gem
Per Steam's own listing, this is a roguelike, auto-battle, NES-style retro RPG in one: a protagonist who died an unfortunate death is granted mercy in the heavenly realm and a chance at a new life, then descends into a dungeon that reshuffles with every attempt, its battles fully automatic, characters thinking for themselves and choosing their own best moves. Growth comes through 'Jewels' dropped by monsters or bought in shops, Armor Gems for defense, Weapon Gems for attack, and Skill Gems that determine which abilities a character's class can use, layered with a Chain system that raises damage on consecutive hits and a Chain Burst that upgrades magic attacks landed mid-chain. Each ending is reachable in roughly 2 to 3 hours, with optional difficulty-boosting items and secret bosses for players who want more, and an original chiptune soundtrack of over 20 tracks by Aomo Akane styled after late-1980s NES music. Made and self-published by MSBgamedev (rendered as MSBgamadev in Steam's own developer field, a one-letter discrepancy from the same publisher name used everywhere else, including the developer's own X account and Steam community posts), a creator who has stated directly on X, 'I am a Japanese indie game developer,' alongside a Japanese flag emoji. Released at ¥920, it is Positive at about 93 percent over 27 reviews (25 positive, 2 negative per Steam's own review API), a paid title, not free, fully launched and not in Early Access, with no AI-generated assets, and per Steam's own content descriptors, nothing sexual. It supports Japanese only, with an English localization still in progress and no set date confirmed beyond the developer's own plan to time it to a Steam Auto Battler RPG Fest event; of its 27 reviews, 26 are in Japanese and not one is in English.

Give it your first passRogue Legacy The critical echo
The origin of this taste: Rogue Legacy, Cellar Door Games' 2013 roguelike platformer, in which dying doesn't end a run so much as pass it on, a randomly generated heir inherits whatever permanent upgrades gold has already bought, and sets off into a castle that regenerates its layout with every attempt. It established the idea that reincarnation and death itself could be the core progression system of a game rather than a loss condition to avoid. journey of reincarnation is not an official Rogue Legacy work, and this lineage is a comparison drawn by this site in outside critical commentary, not a stated influence from developer MSBgamedev, but a hero granted a second life who grows stronger through gems across dungeons that reshuffle with every run carries that same founding idea into a fully automatic, retro-styled battle system.
