OmoDays

OmoDays is a dedicated omorashi sandbox from DelicateSea that centers on a college student whose dorm toilet has mysteriously broken—and who's content to explore the consequences. Rather than seek repairs, you navigate a point-and-click environment where the core appeal lies in unlocking wetting scenarios while managing the risk of your roommate walking in at inopportune moments.

Gameplay revolves around a soft progression system. Early on, you're broke and must grind money through a desk-based side hustle to buy items from the store, which then unlock new scenario branches. The 38+ unique wetting scenarios form the meat of the experience, tracked via an achievement system accessible from the menu. DelicateSea has included sandbox freedom—you can trigger wetting events while performing other activities, which opens up additional challenge-based unlocks. The game also features a Roommate Watch mode that locks your roommate permanently in-room once activated, rewarding players who discover its hidden trigger conditions. Particle effects simulate the visual element of the core fetish, and bedwetting variants (jeans and boxers) provide some environmental variety.

The adult content here is entirely focused on omorashi and wetting; diapers are optional rather than mandatory, and there's no ageplay. The tone is matter-of-fact about its niche appeal—this isn't trying to be coy about what it is. Two CGs exist currently with promises of expansion in future versions. The game supports Windows, macOS, and Linux, and includes cheats accessible through settings if you want to bypass the grinding phase. Expect a few hours of exploration if you're completionist about achievements; casual play will be shorter.
