The short version

RedMoon : IDLE RPG is a free, pixel-art idle RPG about a hero growing stronger under a red moon, auto-battling monsters, collecting equipment and pushing into raids and dungeons. Developed by MYMEStudio and published by Gonggamorecontents, it released 1 October 2025 to a small, Mostly Negative reception, and the reason is unusually well documented: two days after launch, the developer posted its own list of "Known Bugs and Upcoming Fixes," naming a critical issue where "game progress is not saved properly" as the top item. That post is the only update the game has ever received. Reviewers report the exact same save-corruption issue as late as June 2026 — eight months later — with no evidence a fix ever shipped.

Biggest strengths

  • Genuinely charming 2D pixel art that draws praise even from reviewers giving the game a thumbs-down over its bugs
  • Completely free with no in-app purchases found anywhere on the store page or mentioned in the review sample — an unusually clean monetisation record for a free idle RPG
  • The core auto-battle loop is functional and enjoyable in short sessions, according to several reviewers, when the save bug doesn't intervene

Biggest weaknesses

  • A save-corruption bug that can wipe or reset hours of progress is confirmed by the developer's own day-two bug notice and is still being reported by players as late as June 2026, with no evidence of a fix ever shipping
  • No update of any kind has been posted since that single "Known Bugs" notice on 2 October 2025, despite the developer's own words promising a patch "as soon as possible"
  • Power scaling is reported as badly tuned, with several reviewers describing dealing enormous damage in the opening minutes before hitting sudden, punishing difficulty walls later on

Who it's for: Only players willing to accept the real risk of losing all progress to an acknowledged, apparently unfixed save bug; everyone else should wait for evidence the issue has actually been resolved.

Our recommendation: A pleasant-looking free idle RPG undermined by a save-corruption bug the developer confirmed in writing and appears to have never fixed — not worth the risk to your time until that changes.

Introduction

RedMoon : IDLE RPG sends a small pixel-art hero out to grow stronger under a crimson moon, auto-battling waves of monsters, summoning field bosses, and pushing into raids and dungeons for better equipment. It's free to play, developed by MYMEStudio and published by Gonggamorecontents, and it released 1 October 2025 to a small but clearly Mostly Negative reception — 48 total reviews, and this review reads the complete 15-review English-language sample rather than a subset, given how small it is. What's unusual about this game isn't the existence of launch bugs — plenty of small releases have those — it's how precisely and publicly documented the central one is, straight from the developer's own words.

A bug the developer confirmed, then apparently never fixed

Two days after release, MYMEStudio posted the game's only news update, titled "Known Bugs and Upcoming Fixes." Its top listed item, under the heading "Critical Issue," reads: "Game progress is not saved properly (in some cases, progress resets to level 500 after restarting)." That's not a player's inference or a guess about what might be going wrong — it's the studio's own written acknowledgement of the exact failure players go on to describe. And they do describe it, at length and consistently: "Everytime you quit the game, it does NOT SAVE your progress. I lost about 25 hours of progress," reads one review. "The game doesn't save properly. I lost all the progress I made," reads another, dated March 2026 — five months after the developer's bug notice. A third, from June 2026 — eight months after launch — reports currency being spent in a bugged shop with nothing received in return, a related but distinct symptom of the same underlying instability. No further update has been posted since that single October 2025 notice, and this review found no evidence in the sample or the news feed that the promised patch ever shipped.

For a genre built entirely around long-term, persistent progress, a save-corruption bug this central and this well-documented is close to a genre-defining failure. It isn't a balance complaint or a matter of taste — it's the single mechanic every other part of an idle RPG depends on, reported broken by the people who make the game and by the people who play it, with nothing in between to suggest it's been resolved.

What's underneath the bug

Setting the save issue aside, the reviews describe a reasonably competent, if roughly tuned, idle RPG. The pixel art draws real, specific praise even from critical reviewers — "the game looks good and has potential," reads one thumbs-down review, immediately before listing its complaints. The core loop of auto-battling and gearing up is described as enjoyable in short bursts by more than one reviewer. The power curve, though, is reported as poorly calibrated: one reviewer describes dealing "millions of damage" within the first two minutes, only to be fighting enemies with a few thousand hit points half an hour later, before hitting a wall in Hard mode where "the game just dies" and no further progress feels achievable. Additional reported bugs — monsters failing to spawn in dungeons, bosses appearing behind the player character, dungeon tickets consumed incorrectly — read as symptoms of the same rushed, unpolished launch state the developer's own bug notice described.

Value and monetisation

There's genuinely nothing to criticise here: RedMoon costs nothing, and neither this game's store page nor its review sample mentions any in-app purchase of any kind. For a free-to-play idle RPG, that's an unusually clean record. It just isn't much comfort when the thing being offered for free carries a real, developer-acknowledged risk of losing everything you've built.

Final Verdict

RedMoon : IDLE RPG has real, if modest, charm — pleasant pixel art and a functional core loop that several reviewers genuinely enjoyed in the moments the game was working correctly. What this review can't recommend past is a save-corruption bug the developer itself confirmed in writing within 48 hours of release, promised to fix, and then appears to have abandoned alongside the rest of the game — with the exact same symptom still being reported by players eight months later. Being free removes the financial risk, but not the risk to your time. Until there's evidence this specific, acknowledged bug has actually been addressed, this is one to skip.
