...hey wait, I played this last year! I guess the big addition since then is the 3D levels. I'll say for the record that those generally took me the longest to figure out because it was kind of difficult to understand what I was dealing with; honestly for a puzzle game, I'm not entirely sure if that's good or bad. I think maybe the free look mode should allow for up/down rotation? I pretty much agree with Solo Man on the music; it's nice that you added it, but it's also not too interesting. Otherwise, though, it's as solid as ever.
