I disagree with you comparing this to Summertime saga. There is a difference in not liking the content that's being updated, and being AWOL for 6-8 months(Before the teacher content update, nothing happened for like 8 months, only minimal updates which only added a few UNFINISHED sister scenes). Summertime saga is at least consistent to the most part with there being new content to play with each big update, things being reworked, improved, adjusted. This game is nowhere close to STS in terms of the creators quality and consistency.
Edit: Just to add that I really like the art in this game, and I used to be positive about it, but it's simply difficult to support this game when the creator has proven that he's not really capable of consistency with long periods of nothing happening. 4-5 months of waiting to get an unfinished scene with sister and the driving scene with mother that you could get through in 5-10 minutes at most. You cannot defend that or equate it to STS in any way. STS is one of the most consistent and highest quality releases on this site.
