Trappist, a space exploration / city builder game in the Trappist-1 solar system. It is inspired by the classic Alien Legacy, with more modern gameplay in the style of the Anno-series.

I've been working to time an update and demo release with the Steam City Builder & Colony Sim fest: https://store.steampowered.com/app/2769820/Trappist/
