Hydrophobia: Prophecy also has a new achievement, but it seems that the game hasn't been updated yet.
Is really And Yet It Moves that bad on Steam? I tried it on WiiWare and I loved it, also the devs were really nice (I tried it at a convention). I was going to buy it the last day of the sales...
Also, I couldn't stand the Beat Hazard demo. I was very interested in the game, as I loved Audiosurf when I tried it on a buddy's computer (and now is one of the daily deals I'm looking forward the most), but then I tried the demo and then proceeded to uninstall it after trying to finish two songs :lol (Also, I'm very worried now because I felt a little ill after playing it, I think the default visual feedback was way too intense...)
Oh, and you just couldn't exit the fucking demo. I swear, you were supposed to press backspace in order to exit, but instead it opened the game's store page so you could buy the game (as it did when you clicked, but that was what it should do). I had to press Ctl+Alt+Supr and terminate the process :/
