The first pattern for the Glyph lock seems to be bugged. Tried several times, checked the walkthrough, tried the same procedure there several times - still doesn't work. Sad, the game was really good up to this point.
Controls make it seem like the character has butter-covered shoes at all times. Artificial difficulty and the calming, then insulting screen after pressing "Give Up" make this game only enjoyable for masochists. I was gravely disappointed because most of jmtb02's games are amazing, but everyone fails sometimes.
I hope your computer is top of the line. If not, you'll be spending half your time cursing enemies and spikes and the other half for accidentally hitting a crystal or computron. All of the above make it lag for 2-3 seconds each time.
Two other problems: often you can't let got of a a piece without clicking on another, and the link to the site with other games often gets in the way of grabbing a piece. I do like the option to turn the picture off, as that makes it less confusing.
