The game looks pretty interesting (even if in a sense the same as most HS Vis Novels), nice looks characters, neat premise, etc.
But it looks like you threw in the towel pretty quick.  No updates here, your patreon, or twitter in 5+ months...
Plus you list as also for Mac, but the Mac demo DL links to the PC-Demo file.

Hello UsagiSabita.

No, the game is still in development, I just had to reduce the hours because I had to accept a 6-month contract away from my home/studio.

I just got home from a trip yesterday and I organizing my studio to return full-time to game development.

The good news: I have a better PC, with which I can improve all the rendering, videos, animations, etc.

For all those who contributed to PATREON, you will receive your rewards accordingly.

Soon I will launch Ver. 0.1
