O2A2 is ostensibly about efficiency, but that never really bears out in most projects. Cupid's Kiss is very, very tight and still offers some player choice that feels reactive, AND its tempo matches the ebb and flow of the story being told — something you'd be hard-pressed to pull off in 1,000 words. O2A2 devs, pick this apart if you want to actually wrap your head around what brilliance O2A2's restrictions can bear.
