"Ah, okay, I get this, it repeats puzzles until you get 'em. That one's tricky, so I'll just skip it and maybe I'll get a clue from another puzzle and, oh, game over."
That puzzle in the last screenshot on the page is the one that did me in. My brain just said "nah man, no solution" and that was my downfall.
I don't know how I feel about the "only play once" concept, but I will say it's a bold choice! And what better time for bold choices than game jams, amirite?
