The main issue with the game (as of week 12/the 4th of October) was that there was no real "tutorial" or guide for the game. The player spawned in and immediately they are greeted with the first puzzle, with no explanation of controls or anything.

The first version included a big flat piece of land... And that's it. No text no controls no direction, just a chunk of land. 
The first questions I got were "Where am I meant to go?" So I immediately put in a few more trees and I used my floating text prefab to write some instructions and 'lore' in the sky for the player. 

I still saw people not understanding the controls, so I created a second, smaller explanation on a little tablet poking out of the ground with 'vague' explanations for controls, to keep the atmosphere up. This was a mistake, they were too vague and people were managing to finish the tutorial without realising they could pick up the boulder. That, and they were still unsure where exactly to go.

I improved on the tutorial level a lot, and added more scenery as well as a little stone path leading the player in the right direction (forwards).

Here is the updated version so far (as of 13th Oct). I plan on changing the explanation tablets a bit more as well as fixing the issues with the land deformation, but those are still a WIP.
