Quantum Conundrum is many things -- an innovative puzzler, a follow-up project from Portal's Kim Swift, a lesson in bad parenting skills. Seriously, who leaves their kid on the doorstep of a crazy uncle whose house is a labyrinth of murderous puzzles? It also has its share of little annoyances, not the least of which is a poor narrative and puzzles that feature one of my most-hated gameplay mechanics. As such, Conundrum's conundrum (see what I did there?) is that it creates some unnecessary frustration around some really great ideas.
