SO when is the OST going to be released or do I have to download the game to get it ?

Hello! tell me, please, what to do in the fourth chapter, the samalot just flies and what does not happen? I write a review of the game and here it is. http://radikale.ru/full/2017/9/4/276751f80fdd00b102014e3538cd8075-full.jpg.html http://radikale.ru/full/2017/9/4/6eb7ff265020a9633d349f6e52ca91c9-full.jpg.html...

I went through the game and at the end of the game I have a question, is this the final? https://drive.google.com/open?id=0B_Chu6onunMiTXVBQkQwN1Nwc1U

please. Thank you

Is the game gone for good?
