I just played this game recently. I was surprised and wondered if this is a renpy game? It's so wonderful. After researching I found that the game itself has not been updated for almost 2 years but it seems like every day there are comments waiting for this game to return.

Komisari (the dev) posts regularly here in the comments. It has been stated multiple times that a very large update is on it's way, but no ETA has yet been announced to my knowledge. It seems that as a one person dev team, Komisari would rather put out one massive update than a ton of small updates, and it is taking quite a while to finish the next version. Personally, I am perfectly willing to wait for a quality update, rather than get one or two events every week or two.
