Thanks for playing! Yeah the how to play thing was a bit last minute, I was also developing this on a 28 inch monitor, so the text was very clear for me haha! I was debating how best to approach the game, as I ended up with this time trial idea, I thought it best to have it in a way that means player have to practice and get better at dealing with the gravity but I did want to add a grapple/rope mechanic that I didn't get around to!
The digging was the main thing I wanted to get working, it is quite a complex combination of a marching cube algorithm split across multiple threads each of which are handling calls to compute shaders so that it can regen the mesh fast enough, so that took up most of my time :)
