Wonderful little game, perfect example of a pico-8 experience: short, sweet, and surprisingly clever.
I got 13 of the thingamabobs everyone has a different name for them lol before getting the crown; The last two were a lot of thinking, especially the lower left one - tantalisingly close, yet felt oh so far away until I checked again!
Will definitely be in the back of my mind as I'm working on my own current project, especially in how the secrets were in a nice mid-ground of subtle but findable.
