Havendock is a colony builder, with some ideas taken from RAFT. You start on a little island with nothing, and collect resources that float past to start building an ocean dock world. Settlers arrive, and you build a village living on the sea by expanding docks and fulfilling their needs. It's pretty ambitious for a solo dev and it definitely shows its rough edges. I played for a while and although I really like the idea, it looks like the performance is unable to keep up, getting slower and slower as you add more people.
