I've given them all a short try, and basically there are four which are okay.
Empyreal Nocturne was nice. Claustroshpere and Bossinabox are games I have to go back and play a few minutes more to form an opinion, but seem like they might be good once you get into it. And finally PHLOP looks like Armadillo Run, with some extras, but worse graphics (probably made for 1024x768, which would be okay if you could get it out of full screen, now it's all blurry).
Yeah JB, seems like those four are the only ones worth mentioning. Couldn't get PHLOP to work on my machine though, and judging from my internet connection it could be a couple of days before I get a look at the rest of the games.
Maybe beta testing is not part of their curriculum? ;)
