The progression feels a little slow, but I enjoyed playing it! I think the biggest thing I have that's a problem is that it doesn't seem like the tree building really has any use because early game it costs too much to waste the money on, but late game it doesn't have any value as the weather tower buildings do the same thing but better. It is cool that you could have multiple island types to start with though!
Also, since we have similar games, you should try out my city builder!
