This is pretty difficult, but a fun concept nonetheless! A few bugs I encountered was that I somehow click+dragged to generate a black box that can highlight objects, but cannot seem to get rid of it unless I refresh. The other is that the house does not show resource requirements but other items do this fine.

Needing to create additional resources to expand and conquer seems fun, maybe I'll give this another go in the future.

This is "aloft" of fun! 

Cute! I like the floating island as a concept.
