I'm not entirely sure what you mean by updates for a testing scene. If you mean the test scene I have on Patreon, it's just a little behind-the-scenes thing someone can download if they're interested in seeing how the game began. All the status reports on there are about the progress being made on the game's next releases.
I release updates when they are ready, and I endeavor to make the time between each quicker. I am a single person making this, though, so anything that takes me out of commission (illness, family emergencies, etc.) will unfortunately cause some delays.
I can understand if it seems like nothing much is happening from your vantage point, but I do work on this pretty much every day, so progress is being made and there will be new updates soon.
