Same issue as Digital Apprentice mentioned below⬇️

As I passed seventh chamber. I started playing the eighth chamber. After playing it for a couple of minutes I turned off the game. As I tried turning it back on after maybe an hour the screen appeared black with the only thing visible is the controller which you can use to walk as you head the footsteps, but dont see anything. Another thing I noticed when playing the eighth chamber (the couple of minutes the I played), crystals info was showing as 5/5 although I just started level, it was also showing when you pressed pause. Well, thats about it. Fix needed, game is unplayable.
