I’ve mentioned before how much I love Fl0w. Lots of smart people have commented on how the game’s setting and mechanics manage to evoke various feelings.
Additionally, I find that there’s an interesting flirting with death feeling that comes to mind when I’m playing. There’s the sensation that as you go deeper the layers of the world get darker, colder (imagined) and more dangerous; early in the game, the entities that swim several layers below you seem truly threatening. And so in addition to evoking a number of peaceful, positive feelings, the game also sometimes gives me this type of self-destructive thrill…oblivion is below, just keep diving.
It’s amazing that so much springs from such a minimal, elegant game design. I love it.
