The Dark Mage’S Theory Of Happiness 0.17.3 Alpha Public (English, Japanese, Chinese)

The Dark Mage’s Theory Of Happiness puts you in control of Lily, a college student who gets trapped in a weird place called the Prison of Desire. This is definitely an adult game that focuses heavily on restraint mechanics and mature themes, so keep that in mind before downloading.

The gameplay mixes action RPG elements with some pretty intense adult content. You’ll guide Lily through her strange predicament while she figures out what she actually wants. The restraint system is the main hook here, and it’s pretty well implemented compared to other games in this genre.

It’s still in alpha so expect some rough edges, but MUGENlink Works seems to be updating it regularly. If you’re into this type of game, it’s worth checking out. Just don’t expect a polished experience yet.
