I spent an hour in the marble maze, Can not do it. Any serious help?

Heyho everyone, Thank you for checking out Reveil directly on launch date - you are the most dedicated of our fanbase, thats for sure! Unfortunately right now (at 5pm CET 6th of march) we have a small hiccup with the soundtrack of the game - you might not be able to download it right away when you purchase it "now" - it will still be in your library and available once Valve and us have "un-hiccuped" the situation - but for now we ask for your patience, you can still enjoy the game in the meantime :) UPD...

The flask is not in the drawer in chapter 4, I've tried restarting the game and it never appears

Game looks really interesting, would be very atmospheric to have proper HDR support.

The game looks great! Can we save when we want? If not is it autosave? And if so how far between autosaves?
