There's some neat ideas here, but I am not sure if my understanding of how things worked was correct? Am I selecting 4 crystals at start and this is loading a distinct timeline? and then I am supposed to die at the end of that timeline and load a new timeline by selecting the crystals in a different order?
I think this is a really neat idea! i also liked how the ship itself became an object for interacting with the world, but if possible it might make sense to make the above more clear (especially if my interpretation was incorrect!)
