A survivors-like action game where a proud young mage carves through screen-filling monster hordes — and where losing, not winning, is what unlocks the adult content. This is YumYumPlanet’s latest, with heroine design by green TEA., and it’s aimed squarely at people who want an actually playable bullet-heaven grind with defeat CGs as the spice rather than the main course.
The setup is simple but functional: a dungeon has appeared, every mage sent in has vanished, and the academy dispatches its young star Lily Weissstahl — the “Silver Goddess,” a strict, duty-bound prodigy with zero experience with men but plenty of book-learned curiosity — to explore it alone. A trap immediately drains almost all of her magic, and she discovers she can reclaim power by absorbing the residual mana from slain monsters. That’s your gameplay loop, diegetically justified: kill everything, get stronger, push deeper.
What works
The core game is the real draw here, and the circle clearly knows it. This is a Vampire Survivors-style action game built around swarms big enough to fill the screen, with skill picks and upgrades offered at each level-up so you’re constantly making build decisions against the current battlefield situation. On top of that sits a weapon synthesis system — fuse materials, break limit caps, and assemble your own overpowered loadout. Randomized equipment drops give it a proper hack-and-slash loot hook, and community sentiment backs this up: the loot grind is the addictive part, the pacing is brisk, and people report getting genuinely absorbed in “just one more run.” For a genre where a lot of adult entries treat the gameplay as a formality, that’s worth something.
Post-game content is also more generous than usual for a doujin release. After the story, Hard, Hell, and Endless modes open up, which gives the build-crafting and equipment systems an actual reason to exist beyond credits. If you’re the type who plays these games for the numbers as much as anything else, there’s a real runway here.
On the adult side, the structure is the classic defeat-unlock design: lose to the horde and Lily’s “other side” gets revealed through event CGs. The roughly ten scenes cover a solid monster-encounter spread — slime, goblin, orc, and demon-hound scenes, tentacle restraint, an armpit-licking handjob, a wall-bound scenario, and masturbation, with creampies, oral finishes, anal, and outdoor situations in the tag list. The contrast the game is selling — a rigid, self-disciplined noblewoman who secretly reads more than she lets on, undone by the dungeon — is a well-worn dynamic, but the character writing in the official materials commits to it more than most, and green TEA.’s heroine design is the kind of thing people buy on sight.
What doesn’t
Be clear about what you’re buying: this is a game with H content attached, not the other way around. Early buyer feedback says exactly that — the erotic side is on the weaker end, the heroine is cute, and the game part carries the package. Ten base CGs (excluding standing art and variants) is a thin gallery for people who buy primarily for scenes, and since the events trigger on defeat, you’re intentionally losing to see them, which always sits awkwardly against a gameplay loop designed to make you stronger.
There are also a few disclosed caveats worth weighing. The resolution tops out at 1280×720, which looks dated on a modern display. The circle openly states that AI was partially used for some item icons and monster characters — the heroine art is hand-drawn by a credited artist, but if any AI involvement is a dealbreaker for you, that’s your answer. And the store page notes the content partially overlaps with the circle’s own earlier title CIRCLE-WARS, so if you own that one, check what’s actually new before double-dipping.
Who should buy this
Get this if you want a competent survivors-like with hack-and-slash loot and build-crafting first, and a defeat-CG reward layer second — especially if a strait-laced, secretly curious mage heroine getting overwhelmed by monsters is your particular lane. The game officially supports English (and Simplified Chinese) alongside Japanese, so non-Japanese readers can play this without any language barrier. Skip it if you’re gallery-focused, allergic to any AI-assisted assets, or already own CIRCLE-WARS and mainly wanted fresh content.
Verdict
7 / 10. A genuinely moreish survivors-like grind with generous post-game modes and an appealing heroine, held back by a slim scene count, 720p presentation, and adult content that plays second fiddle to the gameplay it’s attached to.
