Conexus

Conexus (2023): Adventure. Available on PC (Microsoft Windows).

Conexus is a short Yume Nikki fangame that follows a young adventurer who mysteriously awakes in a realm of interconnected worlds named the Conexus. Uncover the reason why you were brought to the Conexus, and learn about the realm's history along the way. Or if you don't feel like performing story errands, just treat it like a digital museum instead. This game features 17 unique areas to explore, with lots of weird things to see and people to meet everywhere you go. Unlike the typical Yume Nikki fangame, there aren't any "effects" to find here, instead all of the focus is placed on touring a fully open realm where every path leads to somewhere else.
