I very much enjoyed the demo, but one thing I noticed, spoiler alert, was that when you're supposed to dock in the sub bay by the end of the demo, I failed to do so and opened the gate, drove through it, which sent the sub into a vast empty space and for me it was not entirely clear if this was intended as another anomaly and part of the game or not. Maybe it can be blocked until after the sub has been properly docked? Before realizing what I was supposed to do I spent some time experimenting with trying both ascending and descending in that empty space, thinking it was intended. It did add something to the experience though, to have the hallway suddenly disappear to realize the boat is lost in a void. 

good game 

cannot wait, screenshots look amazing. This game is such a hidden (imo at least) gem and I really feel like its going to do great on steam with a EA and/or full release some day.
