A few days ago (10/3) from discord:
"Hello everyone, we have some news for you. We're very sorry for the delay and the lack of activity, but we're dealing with some personal issues. Until recently, we were completely focused on developing the project and were able to work comfortably here. However, with all this social media, many payments are delayed, many things are lost, and it's truly demotivating. But we're not giving up. We have a clear goal: to tell a great story, and that's what we'll do. Currently, Brax has had to return to work full-time, so it's been somewhat difficult to move forward. We weren't used to having this daily burden, so it's been difficult to make enough progress every day. However, development hasn't stopped; this is what we've been working on. We're structuring the routes more concisely. We'll have three different routes, but this time they'll be more detailed and focused on their progress. Right now, the three routes were intertwined in the main story. Major events appeared very early in the story, which took away mystery and excitement from the rewards. Now, the story will be divided into three distinct axes: Blake's story, Oliver's story, and the story with monsters and NPCs. There will come a point where the story will no longer allow for further interaction with the other actors. This will be the breaking point, where Danna will be completely corrupted and will progress entirely with that actor alone. This means we'll be able to progress through different stories without mixing everything into one long story with many plot holes. The main mechanics remain the same, and this also gives us more freedom to add random events, depending on the story being followed. That's all we can report at the moment. We will continue working and moving forward with this project, which we hold dear."
TLDR:Moving to new engine "RPG Maker MZ" 2 months ago, they said it's doing great. Personal stuff add to delay, but they are working, and will post updates every week now it seems
