Sorry you didn't have time to make your game what you wanted it to be.
I've been there before and it's not the best feeling.
On the bright side if it makes you feel any better, you made an awesome terrain generation tool :D
I really like the way the new tiles pop up and the island expands. It may not be what you wanted but at the very least you made a very cool looking island generation tool!
Good job man! Can't wait to see what the final game looks like!
