Ninja Girl (SHINOBI GIRL -EROTIC SIDE SCROLLING ACTION GAME-) — Honest Review

Reviewed work by KooooN Soft · View on DLsite

A stripped-down Flash side-scroller where your kunoichi has three verbs — strike, dodge, and masturbate — and getting caught means being stripped and violated one animation at a time. This is a hectic run-to-the-goal action game built around a large library of interspecies loss scenes, and it’s aimed squarely at players who want their h-content delivered as a real (if simple) game rather than a click-through gallery.

What works

The core loop is refreshingly direct. You control a girl running toward the stage exit, and the entire game is about threading through enemy swarms using attack and dodge — plus the genuinely unusual choice to make “masturbation” a third command in your kit, sitting on the same level as combat and evasion. It’s a small design idea that gives the game its personality: the erotic theme isn’t just what happens when you fail, it’s baked into how you play when you’re winning. For a project this minimal, that’s a smart hook.

The real draw, though, is sheer volume of content, and it’s volume that grew enormously over the game’s life. What started as 17 enemy types and 34-plus animations expanded through years of updates into 21 enemies and 44-plus animations, and that count includes a lot of variety beyond the base loss loops — speed variations, ejaculation and climax states, masturbation, aftermath scenes, and multiple dedicated game-over screens. The being-hit progression is a nice touch too: the first hit tears your outer clothing, the second strips the underwear, and the third takes it further, so the visual escalation tracks how badly a run is going. Content is overwhelmingly interspecies, with tentacle and beast encounters plus a roster of bosses (a Fallen Angel and a Doctor were added in later patches) to break up the standard enemies. Clear all six stages and you unlock a gallery mode, a harder “hell mode,” and stage select, which gives the animation collection a proper viewer and gives skilled players a reason to keep going.

It’s also worth crediting how much this game was supported. The update log runs for years and keeps adding real material — a full-nude costume, new cosplay-ball enemies, a pregnancy (“bote”) state layered onto multiple game-over screens, an easy difficulty for people who bounce off the action, and repeated bug fixes and quality-of-life tweaks like saveable options and smoother gallery controls. Voice work is present too, with Tiger Lily voiced by Ryou Suzuki, and there are sound effects throughout. For a doujin action piece, that’s a lot of ongoing care.

What doesn’t

The biggest practical problem is performance, and the developer knows it — the product description itself warns that the game runs heavy and tells you to download the trial first to confirm it even runs on your machine, noting the full version is considerably heavier than the demo. That’s an unusually blunt admission, and it should be taken seriously: a side-scroller that chugs is a side-scroller that fails at the one thing it needs to do. Being built in Flash also makes it an increasingly awkward proposition on modern systems, so factor in some setup friction before you expect it to just work.

Beyond the technical side, the game is exactly as simple as it advertises. Three commands and a run-to-the-goal structure across six stages is a thin skeleton, and if the animation content doesn’t land for you there isn’t much else holding your attention. The content itself is also narrow by design — it’s dub-con interspecies material first and foremost, so anyone who isn’t specifically here for tentacles, beasts, and forced loss scenes will find little that’s to their taste. And there’s no BGM at all; you get voice and sound effects but no music, which leaves the action feeling a touch bare even when it’s running well.

Who should buy this

This is for players who specifically want an action-game framing for their h-content and are into interspecies, tentacle, and dub-con material — ideally people willing to run the trial first to confirm it performs on their setup. If you like the idea of earning your animations by actually dodging through a stage, and a deep gallery of loss scenes is the payoff you’re after, this delivers on that. If you want story, kink variety outside its core themes, or a game guaranteed to run smoothly out of the box, look elsewhere.

Verdict

6.5 / 10 — a charmingly single-minded, heavily-updated action-gallery that’s held back mainly by its own admitted performance problems and Flash-era baggage, but if its interspecies content is your lane and it runs on your machine, there’s a lot of it to enjoy.
