1. Reading the announcement. If you are interested and it is not version 0.001 of 50 Mb, you can download it.
2 Unpack it, run it. If within half an hour what is happening on the display did not cause any response in your soul - mercilessly delete.
3. Repeat point 1.
According to the theory of probability, sooner or later will meet something worthy.
Although we must point out. Sometimes not badly started projects begin to degrade (in my opinion) and eventually lose my interest. And also sent to the trash can. And these are well-known and popular projects - Summertime Saga, Taffy Tales, Love & Sex Second Base, Reunion (by Karabinek).
But even taking into account possible subsequent rejection, you can find something interesting for you personally by trial and error. I have time to familiarize myself with 3-4 projects a month, no more than that. And at the end of the year I save only 5-6 games and VN. So a good project is a rarity.
