I hope this will help. This was on their discord channel, posted last Feb 11, 2020. I'm not entirely sure if this is true but I hope it is and I hope I'm able to share this to you all, because it's really hard to find an update to this wonderful game.
UPDATE by @carafox
Hello! wave Quick update from me personally. Massive KUDOS to my team members for finishing that massive Rui script, getting the point system working, getting amazing sprites done, etc. Hardest parts are done done! clapclap What's left? All the easier stuff. Fixing bugs, running QA, finishing CGs, finishing content for ASL, and finally getting approvals again from App Store & Play Store. Popped in here to say hello and that we are moving this along every single day wink . It's definitely top of mind for me personally to get Rui shipped to everyone especially since I had some hiatus. ship
