I really like the open space, the first place I went was up the mountain, and seeing the crystal in the distance reminded me of hunting down a star piece in Breath of the Wild. I was also playing around with the game physics a bit and was able to run up and float off the mountain.
The only trouble I had was interacting with the crystals I would click my mouse and I would see it move but I didn't realize that I had to hold the mouse down to keep it.
