A few notes on DJManiax, it's actually not as hard as I thought it would be. If you are stuck collecting crazy stars to unlock the 5 and 10 crazy stars songs, go for Dash Hopes 3, it's not that hard (the tracks by Hoeloe are way harder imo), and you'll get a little surprise. Also, you don't have to beat every track on all 3 difficulties to get the 100% completed medal. Right now I have 81 clear points and I still have to beat Eight Circles by Hoeloe, so I'm missing the 'True Completionist' medal. I'm not a huge fan of the music selection in this game. Some of the tracks were nice/awesome, but others, well, let's just say that after years of going to experimental electronic music parties (and performing on some of them), a chopped Amen breakbeat and dblue glitch just doesn't excite me at all anymore. But I can tell the authors spend a lot of time on this game, and I had fun playing it, so that's the most important thing.
Also, Icy Cave of Frustration is frustrating. =)
