I really enjoyed this game! Beautiful and detailed art, mood is perfect, theme is executed really nicely.
However, it has a few rough edges.
I took a long time to understand all the mechanics. For example I was confused that water didn't appear when terraforming (because I was placing them on rocks, which turns them normal land).
The game is very difficult, but it seems that the difficulty varies wildly depending on your generated map. The lose states can be quite unsatisfying. For example, if you run out of metal and just can't build, you feel doomed. Same if you just can't build enough houses.
There are lots of other little things that could do with polish and fixes, but you've mentioned you're working on version 2--I look forward to playing it.
