I Have a Stomachache (MuMu-Factory)

Editorial Review

★3.2 / 5 — henhenta editorial rating (our own assessment, not the DLsite official user score)

This is a scatology-focused arcade game that strips away pretense to deliver exactly what its title promises: a niche fetish experience built around gastrointestinal humiliation rather than conventional sex acts. In the landscape of adult games, where sexual mechanics typically dominate, *I Have a Stomachache* is refreshingly honest about its specificity—it’s less visual novel and more specialized application, targeting an audience that values scenario immersion and physiological detail over narrative complexity.

The structure is straightforward and mechanical: mini-game progression gates access to the core content, a common framework in doujin games that provides pacing without bloat. The pixel art presentation suits both the budget constraints of independent production and the retro arcade aesthetic that complements the game’s deliberately unglamorous subject matter. The inclusion of multiple selectable girls in the full version (with one available in the trial) suggests some attempt at replay value, though the core loop remains static.

What distinguishes this work within its subcategory is the absence of sexual intercourse—a deliberate creative choice that keeps focus laser-tight on the enema scenario itself rather than diluting it with conventional adult content. The scatology tag isn’t window dressing here; it’s the entire product. The mosaic censoring in the trial signals respect for regional regulations while maintaining the essential visual information the fetish requires.

This appeals precisely to players seeking uncomplicated, scenario-specific content without narrative filler. The trial-first recommendation is sensible given the work’s extreme specificity—compatibility checking and content confirmation matter more here than with mainstream titles.

For those whose interests align with this niche: a direct, unapologetic execution of a particular vision. For everyone else, the specificity itself is the warning.
