Dang I even read your comment in discord and forgot to go back to the right island and had to do the first one twice 😄
Second one I died to a boulder while crouching and seem to have broken things. I like the concept of different age themed obbies. Some of it is a little silly (why does hitting the side of spikes or a wall kill me?) but that's par for the course with this type of thing.
One thing I'd really like is more feedback around the time traveling and when you've successfully done it or not. And obviously the game should keep track of your island for you. But this is a fun game and the environments are really nice!
