1. Corruption Ending is done and only missing a last couple of CGs on the art side
2. Development of the content for the good ending and side content to help get it is currently in progress.
3. Estimated 1.0 release is currently the upcoming January.
I plan to further work on the game after the 1.0 release through the addition of additional side content, mostly focusing on further progression certain h-event chains, increasing the number of available choices, quality increases, etc. 1.0 will be by itself a complete experience, so even if I were to get hit by a bus after 1.0 is done and no further content wouldn't be produced, it's still already a properly finished game.
