alice, for lvl 63: First, get the "P" promoted exactly twice, making sure the "N" gets just one promotion. When you eventually do the right half, be sure to hit the switch with the "K" before starting on the "G".
Absolutely needs a way to lock tiles. Not including that needlessly frustrates the gamer. It's boring having to memorize which tiles are correct, and just tempts me to keep track of it on paper. Let me mark the correct ones so I can spend my time peacefully deducing, rather than hoping I've remembered correctly.
