While I'm far too busy to give a proper review yet, I want you to know that your game is amazing, unique and really special. I can't believe the amount of content just for v0.3, I know you said there would be more but holy crap. And did you finish the plot already or something? There's no way you're making this up as you go cause holy even the plot gives me goosebumps.
Like you said there isn't any other game like this, and even for the next 1 year whoever attempts a game like this will most likely abandon or won't be able to maintain such high quality like you do. Seriously, those who love this genre - me being #1 - will absolutely love this game. I wanted to quickly say this out so that you remain motivated, I hope you and this game gain more support and it continues as amazing as it already is.
Now there are very small quirks and improvements I personally feel could be made and I will save that for my overall in detailed review that will come out shortly. It's pretty easy to write a review than make a game, so my review should have some constructive criticism (Like maybe re-working chapter 1 a bit as that's where most people seem to be getting bored) but mostly just indicating how great this game is and how much I loved it. That way you also know what I found best in your game (hopefully from others too) and what I didn't enjoy as much as I enjoyed the rest.
This game feels like a gift for christmas lol, did not expect something so good. Chapter 2 and 3 were amazing.
