Overall, I like the game. The levels get a bit tedious as you progress through the hard ones, but then you get the extra levels, which are crazy, and completely pulled my interest back in the game! I particularly liked the one where you're zoomed and locked into the bottom left corner of the game board. Although the map that did a 270º spin on every click was kind of the line for me as "too much spin". None of the other spinning maps invoked nausea, and they were a fun twist.
I think the names are enough of a hint for most of the achievements, but I personally, can't quite figure out leet and obsession. I reset and played through twice, but that didn't do it. Any hints?
