Wow! I was blown away by this! This is so well made! I love these types of puzzle games! Once I reached level 4 where you had to bridge it over to the other island I was like "oh yeah, this is something special". Really great work!! Amazing all around!!
My only real suggestion would be to not let the farmers fall off of the islands. Too many times I had to undo just because I held the key just a millisecond too long. Other than that, not much to say! Awesome work..
Oh, actually 1 more thing, there doesn't seem to be a way to exit the game from the main menu? I tried escape, end, and looked through all of the sub menus but couldn't find anything. Ended up having to use alt f4 instead.
