I wasn't expecting to see a puzzle game here, and I think this does a pretty good job of being horrendous while still recognizably a puzzle game. The puzzles are obtuse, tedious, and frequently the actual objective is completely unclear. Though I should mention that I'm so bad at puzzles I wasn't even able to figure out the word one.
It almost feels like a waste. While conventional, some of the puzzles are mechanically interesting, and the premise is actually intriguing. But I suppose that wasted potential makes it worthy of a GBTK game in its own way.
