Steam achievements did not transfer from Prologue to Demo

Let's see... I've finished the demo planet, found and smelted all the ore, completed the Taskmaster's list, unlocked all skins, gotten all the Steam achievements, maxed out all the benefactors, and have all the planet perks. Yep, think I've gotten everything worth getting in the demo aside from a few in-game achievements beyond the Steam achieve thresholds. Time to gently nudge the dev into giving us an ETA or roadmap for releasing the full game. I'm aware he had to rejigger a few things in converting ...

please ship it

Free to play is always a red flag for me. One look at the poor state of mobile gaming will tell you why, so what's the business plan for this game?

Whats the differences?
