I added a few more obstacles, but the nature of the obstacles means that mesh colliders don't work properly, so at present obstacles like the astronaut don't offer physics collisions. I will have to add basic colliders to these objects, which is not desirable as the objective is to make every visible space passable and every visible object collidable. 

I added an instructions page, which basically explains how to use the save system for now.  

I've added some art to hopefully inspire visions of space FPV into players. 

future plans: 

I may try to set it up so that saving and loading only accesses those saves from that scene.  This will mean that saves created in that level will only be accessible in that level. 

I hope to have some more placeable objects that remind the player of realistic space environments. I will set the drone to work at half-power on all lateral angles. The rockhopper will stay the same. 

I plan to update the webGL version to have object placing, as well as a lunar surface instead of a cube room. Object placing will be fairly limited in the webGL version, but it will be available.
