Sleep Monitor is an adult parody management simulator made with Unity by DashyDash and presented in 3D CG style. The setup centers on Cappie, who is asleep while you choose whether to quietly observe the scene or take advantage of the situation. The interface gives you choices around the sleeping character, and the game presents a parody tone. It emphasizes simple choices rather than a serious story.
The current build is Demo v6a, released September 10, 2026. It runs on Windows in English and is uncensored. It is a demo build rather than a finished release. The latest changelog entry for this version notes a plot-related change. Earlier demo notes mention environment tweaks, hints, bug fixes, and animation improvements, but the current version summary is brief.
Developer's description

I felt the game was a little too difficult,
We've lowered the cost of sleeping and made it easier to remove clothes.

Quite straight forward sleep sex parody of MiSide. As of Demo v6 you only have access to Cappie. To be honest there not much to write about. If you played a 3d sleep sex sim, you played them all. And…

Unga Bunga Translation: "So it's not bad, very straight forward and for a demo it runs okay. But It's not perfect. I'm giving it 4 to be generous but I'm expecting better to come at the same time. - Gameplay…

This game is great. All I can say about it that needs to really be worked on is the accuracy of where to click/drag during different poses and different POVs. Everything works as it should, you just got to click…
