Abandoned game? Any news, creator ?
Dev posts development updates more actively on Patreon. Major dev logs containing important information are usually free to view even without subscriptions.
The most recent free one is Dev log #34 from back in March. In it the dev mentions how the update is about 50% complete. Assuming he has kept the same pace the update should release around July 1st for subscribers, and around July 24th for free. However, I am not subscribed and cannot read the latest dev logs so assuming he has hit a few snags in development (or took a break or two), Chapter 4 could very well release in August or later.
As far as I am aware the dev pretty much works on the game by himself with someone else doing some edits. So it takes time for updates to come out. Especially considering he seems to value both quality AND quantity. Each update basically contains another 40,000ish words, and phenomenal renders/animations. All without sacrificing the overall quality of the story. If you want proof, just look at that second to last image there. You can quite literally count each and every pore on Eve's skin. There is absolutely no reason to render it at such a high quality, yet the dev did it anyways. And I am forever grateful for all the work he puts into the game even if it means a longer wait.
