Hey dev, if you ever see this, I hope that half the dev note is just an exaggeration. Please don't actually overwork yourself to get this done. People get a lot of shit for being slow or for abandoning projects, but game development or even just writing takes a lot of time and effort. If you burn out, your quality is going to suffer and all the added stress is going to snowball. If you have to step away for any reason, that's okay.
That said, I have to agree with
Aristos that the overview and the preview images need a bit of work. If you really have an outline in your mind, I encourage you to get it down on a physical or digital medium if you haven't already. You don't want to spend days writing a scene only to forget that really great idea you came up with for the next part. And if you're looking for feedback, you'll want to get as many people's attention as possible, and you can't do that with a vague overview and a few head shots.
