Super clean. I'll be taking inspiration from you in the future when I'm defining goals and verbs in gameplay. Thanks for a fun few minutes and what will be many more fun minutes of thinking about the themes and mechanics at play here.
There's elegance in the mechanics of a different sort here, and one that I'm not used to thinking in terms of. I'd love to see how your mind works to be able to roll with an idea like this :)
Great work!
