World looks comfy and promising! Takes me back to early 2000s or so.
A little tutorial or screen where a user can see controls would be ideal, I just clicked buttons until something happened.
The camera can clip through the walls of the cave and everything gets dark.
I jumped off the edge of the world because of course I did, and didn't really get a game over or anything, it just permanently had the camera looking at the clouds. Then I clicked "load game" and it crashed.
