Thanks! I agree the game loop is the weakest part. But by the time the water is overtaking the trees, the idea is that you'd have a raft assembled and be standing on it. I added the sharks ability to destroy/shrink the boxes later on, so maybe it's too powerful and so the raft gets destroyed too easily. And maybe the setup time before the water starts rising is too long, and it rises too slowly. These are the things I was working on when the timer ran out!
Anyway, glad you liked the aesthetic and music and stuff! The island is cool, it's a fun place to hang out :)
