Well it may not have followed the limitation but with a premise like "an island management game but on a recursive island," I could not care less. What a fantastic premise! It's really inventive. The gameplay was enjoyable, though I had difficultly understanding where I could and couldn't place things at first. It wasn't until I gave up and went as deep as I could that I even saw a patch of trees, which made me understand why I hadn't been able to place a lumber mill before. The ambiguity around when/where you can place things can be frustrating, but it was enjoyable otherwise. I really hope you expand on this project, because I'd love to see what it becomes.

The atmosphere and concept is awesome, just took me a bit to understand my goals/why I could or couldn't do things. Would be nice to have some feedback about being only able to build on specific 'layers' as I spent a while clicking everywhere I could to build something, and even when I did understand it somewhat I still had to trial and error build spots. Also wish I could zoom between my 'layers' a bit more quickly. 

There are only 2 things I want to point out: the zoom animation is very slow, trying to go back from the last level (I presume, couldn't go deeper even though I had enough people) was a bit tiring and I can't figure out how to build a ship, everywhere I try it's red :(

Now, for the good parts - it's very pretty, has a lot of atmosphere and the idea is awesome, I wanted to espace and I need to know if there's more than 20 levels (I think it was at requirement of 100 when it stopped). Great job, please keep going, it's such a unique idea!
