I did a video thingie on this! I loved it ^^
A downloadable game for Windows, macOS, and Linux
In Yume Nikki: Date Poniko! It's exactly how it sounds; you date Poniko!
Playing as Madotsuki, you must attempt to get Poniko to like you! ... That's it!
this was something i just threw together on a whim, it's pretty short. (super short.)
Should be as simple as unzipping and executing it. Make sure to have the font installed.
