This is the type of mission I can wholeheartadly dig: a simple, but pretty unique concept, implemented in a decent way. Now, it's important to note the gameplay is pretty much a quick save/quick load fest thanks to the engine's unreliable platforming - but I still think it's very much worth to be visiting at least once, because it has a strange, almost dreamlike atmosphere. The setting is the usual City we all know, but at the same time in a unique way that feels like we haven't witnessed in any other mission.

Falling, In Love should obviously not be taken seriously - but to my very own surprise, I gladly do. The story is paper thin, but fun, the gameplay is clunky and minimal, but unique, and the atmosphere is the usual, but in a pleasently strange way. I love it.
