I love any games involving hexes - it's rare to come across a truly fresh mechanic. You've managed to create something original. at least, the idea of connecting the main landmass to distant tiles feels unusual and intriguing. It would definitely be worth developing this concept into a full-fledged puzzle game.

This is nice from a cozy game perspective, but the game definitely needs a few words explaining what we do and why the towers are there.

It's funny, but there needs to be some kind of gameplay goal. It's good that there are black obelisks, but they're not enough, and as far as I understand, they appear randomly.

Perhaps it would be a good idea to reward the player for building closed areas (instead of long lines like mine).

I discovered an undocumented zoom feature.
