Reviewed work by Elzee · View on DLsite
A roguelike dungeon crawler where you play a policewoman named Olivenia descending into a sealed post-apocalyptic zone, choosing every run between spending scarce firepower or taking the riskier route of physical “technique.” This is the sequel to Elzee’s earlier Tunnel Escape, and it’s aimed squarely at people who want their combat-rape content built into an actual resource-management game rather than bolted onto a gallery viewer. If battle defeat scenes, cross-section anatomy, and monster-breeding mechanics are your thing, this is one of the more mechanically serious takes on it.
What works
The gunplay-as-resource-economy loop is the backbone here, and it holds up. You’re managing limited ammunition, explosives, and healing items across stages, and the game is genuinely built around the tension between spending those resources and conserving them. Weapons have distinct characteristics you’re expected to exploit — precise sniping for one-shot kills versus sustained suppression — and the skill tree runs to hundreds of unlockables. The difficulty curve front-loads its pain: the early stages are the tight part, because you simply don’t have items yet and have to lean on interrupting enemy attacks with kicks and shots to preserve supplies before boss fights. Once you’re past that and can afford a machine gun and keep ammo topped up through purchase or crafting, the run economy opens up considerably. There’s no death penalty, which is an unusually forgiving choice for a roguelike and makes the whole thing far more approachable than the resource pressure suggests.
The H content is structurally integrated rather than gated behind a separate mode. The flow is consistent — harassment, then restraint, then a failed escape attempt, then penetration — and the escape attempt is an actual mechanical beat, not a cutscene. If Olivenia is still a virgin, vaginal penetration can be resisted by button-mashing; anal penetration cannot, and a substantial number of enemies in this entry randomize which hole they go for, which is a meaningful escalation over the previous game where anal was rare. That’s the kind of design detail that makes defeat scenes feel like a risk you’re actually taking rather than a reward you’re farming.
The scenes themselves are fully animated with cross-section views, detailed facial expression work, effect layers, and controller rumble on climax. As Olivenia accumulates contact with enemies, she unlocks a wider range of sexual techniques, opening up situational content — foot licking, vore, tickling, milking. The breeding system is the most interesting mechanical hook: creature seeds can be conceived from internal ejaculation, and different seed types shift your stats up or down, which means you can build around it. Choosing to abandon virgin-only play unlocks genuinely strong skills — reduced contamination gain, or a guaranteed-pregnancy skill that deals 25% proportional damage — so purity is a build decision with real opportunity cost rather than a moral flag. The pantyhose costume patch ships free with the work and is well handled: the outfit changes both how enemies react and how Olivenia herself responds to stimulation through the fabric, and there’s a thread running through it about whether she conceals any of this from her childhood friend Noah.
What doesn’t
The seed system undersells itself badly. You can conceive as many creature seeds as you like and the standing sprite never changes — the only visual acknowledgment is a bulge visible in the birth scene CG. For a mechanic this central to the build variety, having zero persistent visual feedback is a real letdown, and it’s the kind of thing that makes the system feel like numbers rather than a state you’re living in.
Some content is thinner than the fetish coverage implies. Scenes where Olivenia’s boots come off are notably scarce, which will disappoint anyone drawn in by the foot-related tags. The parts of the description covering the story beyond the main line — the endless nightmare depths, the random event with the crying girl you can choose to help or walk away from — are structured as replayable content rather than authored narrative, so if you’re expecting a substantial written story you’ll find the framing thinner than the mechanical depth. There’s also a disclosure worth knowing about: some background images in the work include AI-assisted processing. That’s declared upfront rather than hidden, but it matters to some buyers. Finally, one weapon — the auto shotgun — is effectively a hidden item, obtained by noticing that a police corpse vanishes while grinding the sewer stage and then killing the zombie it became down a side path. It’s one of the least awkward weapons in the game and there’s no signposting toward it at all.
Who should buy this
This work is Japanese-only — there is no English version, and the menus, skill descriptions, and story text are all in Japanese. That said, the balance of this one lands in favor of non-Japanese buyers: it’s a gameplay- and animation-driven roguelike, and the core loop of shoot, manage ammo, avoid grapples, unlock skills reads well from icons and numbers alone. A texthooker or machine translation will help considerably with the skill tree and the creature bestiary, which contains the actual strategy information, but you won’t be locked out without them. What you’ll lose is the Noah subplot and the flavor writing around the scenes. If you buy games like this primarily for animated defeat content and build-crafting, that’s an acceptable trade. If you want to follow the emotional throughline the description advertises, you’ll need reading ability.
Verdict
8 / 10 — a mechanically substantial roguelike where the H content is wired into the risk economy rather than decorating it, held back from higher by the seed system’s total lack of visual payoff and by story content that’s thinner than the combat depth.
