I played the demo/playtest and it was pretty cool. The physics-based building makes expanding your settlement a bit of a puzzle, especially paired with the resource management of researching new technologies and keeping your settlers fed and happy.

I will say I think there should be difficulty settings or customization sliders. Towards the end of the demo it gets harder and harder to feed your growing population.

ETA: resource building output needs to be increased as well. Raincatchers produce one unit of water every 2:30 minutes, only during a rainstorm that maybe lasts 5 minutes tops for a long one.

This looks like Raft. Only with actual physics. Neat
