What a goddamned game. What a strange, beautiful, intense experience. I let go of trying to three-star everything and just decided to go through all of the levels once or twice before moving on, and it's a far more enjoyable, enlightening game when you're not so hung up on one trophy or one three-star target time. Since every level is so different, you can find a level mechanic (or just a set of sounds) that clicks with you, and you can just play until your senses simply can't take anymore.
This is the most exhausting game I've played in ages. It's such a weird blend of reflexes, focus, and just letting go of focus to vibe with the level that I can't play for more than 15-20 minutes before having to take a break.
Also, as a fan of synesthesia-inspired games like Rez, Every Extend Extra (see avatar!), an Minter's stuff, I actually find a lot of the "drugs drugs lol" one-liners in discussion of Dyad really tiring and dismissive. I've never done any drugs in my life, and I love these kinds of "overload the senses" games. Even the PSN "games have reached a new high" double entendre made me roll my eyes a bit.
That said, after playing Eye of the Duck, I think any "drugs drugs lol" comments are entirely justified. What a goddamned mind fuck. I felt like my PS3 was trying to reach out of the TV and strangle me.
