Great concept, and very well put together! I enjoyed playing, and the animations were beautifully integrated.
Some feedback to improve: I would find a way to increase the text size in the settings. Another thing I would alter is the beginning of the gameplay. It took me a minute to understand, so when my buildings started falling, it felt like I was too late to recover. Having a start scene with a settlement falling would help with that, or making a couple of chunks fall more obviously at the beginning would help as well.
