Why players say this

Steam review verdict

Fun, addictive roguelite bullet hell with gorgeous art and great value, but adult content feels lacking and the demo may be better.

What players like

Fun and addictive gameplay: Reviewers widely describe the core gameplay as addictive, rewarding, and genuinely fun to play. Many highlight the solid gameplay loop and the ease of getting hooked.

Great value and content: Many reviewers feel the game offers enough content for its price, with the full release adding substantial content and difficulty over the demo. The price is considered fair or even generous.

Beautiful art and character designs: The artwork, character portraits, and overall art style receive high praise. Reviewers find the designs unique, likeable, and visually appealing.

Futa and adult content praised: Many reviewers appreciate the futa content, noting it is rare and well-executed. The game is commended for correctly portraying futa and offering customizable nudity.

Excellent music and soundtrack: The music is frequently praised as good, well-chosen, and unexpectedly outstanding. Several reviewers specifically call out the catchy BGM and great soundtrack.

Common complaints

Insufficient Adult Content: Multiple players report that the amount of lewd content is too low, with H scenes being lackluster and thin in practical value. The adult material is not baked into gameplay and feels separate and underwhelming.

Demo Was Better Version: A large number of reviewers feel the full release is a significant downgrade from the demo, with worse upgrade systems, starter units, boss readability, and overall polish. The demo's unlocked save data was also lost in the transition.

Frustrating Progression and Economy: The progression system and resource economy need serious rework, with heavy grinding required to get mods for the next chapter. Building specific teams around synergies is extremely expensive in biomass, leaving little left to upgrade characters.

Saws Are Overpowered and Broken: Self-destructing saws have massively increased speed and range compared to the demo, can change direction to chase the player, and their explosions create no-win situations with other saws. Easy mode does not make current boss fights easier against them.

Overwhelming AI-Generated Art: Players strongly criticize the heavy use of AI for artwork, music, and H-content, describing the CG art as AI-generated slop with an obvious 'made by AI' feel. The store's claim of no real-time AI content is disputed.

Gameplay and performance

Roguelite bullet hell gameplay: Core gameplay blends roguelite progression with bullet hell shooting, featuring auto-attacking and wave-based survival. Many reviewers compare it to Vampire Survivors and similar horde-survival games.

Upgrade and skill tree systems: The game features extensive upgrade systems, including skill trees, talent trees, and weapon upgrades. Players can unlock new machines, girl types, and synergies using points earned from stages.

Build variety and synergies: Players can create diverse builds using weapon combinations, character synergies, and upgrade choices. Specific synergies like matching attack types or using laser and bounce mechanics enhance team effectiveness.

Customizable genital and gender options: The game allows players to choose between futa, female, trans, male, and other genital types for characters. These settings affect portraits, story moments, and can be changed anytime in settings.

Character creation and customization: Players can create and customize characters, including body skin types and genetic traits. However, some note that character creation is mostly flavor and the character may not appear in battle.

Performance falls short of 60fps: A reviewer noted that the game does not run at 60 frames per second. This may indicate technical optimization issues or hardware limitations.

Audio too loud and obnoxious: One player found the game's sound design to be excessively loud and unpleasant. This could affect overall enjoyment for some users.

Recommendations

Positive overall recommendation: Many reviewers give a thumbs up, love the game, and highly recommend it. It is considered one of the best h-games of the year by some.

Gameplay over NSFW content: Many recommend the game for its gameplay rather than its adult content. Some suggest ignoring the hentai or that it would be more popular without NSFW elements.

Try the demo first: Multiple reviewers recommend playing the demo to get a feel for the atmosphere and gameplay. This helps players decide if the game matches their taste before buying.

Recommended for roguelite fans: Reviewers recommend it for fans of Vampire Survivors-style auto-attack bullet hell with roguelite elements. It is praised for deep roguelite gameplay but may not appeal to those not into roguelites.

Worth buying at price: Several reviewers consider the game a steal at the price they paid and worth a buy. Strong value for money is a recurring theme.

Buying context

Game completion: 10.0h.

Story completion: 8.5h.

The strongest direct reports describe the game as immediately addictive or hooking, while some players report notable early progression, unlock pacing, and onboarding friction.

Friction: Boring early game and progression; Evolutions take too long to unlock in early game; No tutorial or explanation when players are thrown into gameplay; Tedious rerolling without built-in QoL bans; Progression system and resource economy need a serious rework.

Player profiles

Gameplay-First Roguelike Fan: Plays short offline runs, dodging and destroying simple geometric enemies, and evaluates the game on its mechanics and loop rather than its NSFW scenes. Motivation: The casual, low-commitment bullet-hell roguelike combat loop itself, with the adult content treated as an optional extra rather than the reason to play. Stance: buy.

Futanari NSFW Enthusiast: Plays primarily for the adult artwork and scenes, treating the bullet-hell roguelike action as the vehicle that carries the niche content they actually came for. Motivation: Accessing rare niche adult content, specifically futanari scenes, that is hard to find elsewhere in the genre. Stance: buy.

Build-Optimizing Grinder: Grinds toward a single high-value upgrade that every build wants, timing and prioritizing progression around that power spike rather than playing for the moment-to-moment combat. Motivation: Reaching and exploiting the meta-defining upgrade that effectively unlocks the 'real' game, and optimizing around it. Stance: sale.

Other review notes

Full version improves demo: The full version is generally seen as an improvement over the demo, adding more content and better presentation. Some users note differences in atmosphere or the first mission compared to the demo.

AI-generated art and music: The game uses AI for art and music, which has sparked complaints. However, some reviewers note that the quality is clean and there are no obvious artifacts.

Gameplay over story: The game focuses on action and gameplay rather than story, with lewd elements being secondary. It is described as an actual action game, not just a jerk-off game.

Potential for community content: Reviewers see great potential for community-created levels and mods, and hope the developer continues to support the game with updates and DLC.

Playtime and completion: Players report varying completion times: around 5-6 hours for normal mode and about 10 hours to fully unlock everything. Some feel the content is short despite the fair price.
