This was very fun and satisfying to finish. It was difficult, for sure, but I like that the game trusts players to figure out how mechanics connect together on our own. I was scratching my head a few times, but the reachable areas of the world slowly expanding coupled with the subtle visual hints got me through it, and the connections always felt obvious and fair afterwards. Superb level design. I would love to see this game continued into a series of levels with a narrative.
