This was a great game and I love how it looks, but I'm not sure if I reached the ending or not. How things went for me: After messing around a little I ended up in this place with a toppled spire, and then I saw this thing in the distance and started walking towards it, and I heard a sound that slowly grew louder, and when I thought 'something will happen now' I fell off the edge of the map surrounded by cubes and respawned at the starting point. After messing around some more I learned that falling off the edge takes you back to the starting point each time. 

...And after that I wasn't sure what to do, so I stopped playing. I liked what I saw, though.
