Cool game!
The graphics are cute and the gameplay is intriguing. The music is also okay, albeit a bit repetetive (you can hear it loop pretty obviously unfortunately).
I think my biggest complaint would be that the camera is completely static and you have to click a few times to get to the place you want to go to. Especially starting when you've built the first elevator. I was stuck there for a moment and didn't know how to select tiles on the seconds layer (I found out that you have to click on the island first, for anyone also stuck). The gameplay also gets a bet boring after a while since there is no progression to really work towards.
But looking at the timeframe that was set for the jam, I think you all did a pretty good job! I definitely had fun playing this!
