Hi!
So you should probably disable depth test for the Label3D in the tutorial. It is almost impossible to read the texts!
The SFX for button clicks is really harsh, also some crossfading for the music would do wonders, because there was some serious pops there too.
I would have loved to see if I can reach a rock or not, with some indicator on the crosshair perhaps.
Maybe some dark sound effect from the lava when it gets closer would have been cool too. I was never looking down, so I had no idea of where the lava level was.
I managed to climb to the top at last!
