Great game
I started playing this game in hopes of finding new challenges and additional features compared to the older Shift titles. I was not disappointed. Not by a long shot.
The game play was fluid and the puzzles were mind-bending enough to challenge me, but not obscenely difficult either. I especially like the incorporation of box-pushing and shifting. It added to the already great game series that I hoped would continue into this one. In addition, I enjoyed some of the extra little mini-games thrown in. They're not required to progress, but rather there to expand upon the game.
However, despite these positive points, I must also agree with my fellow gamers about the lag that seems to pop up more often than not. I played the game as far as I could and honestly didn't experience any lag at all. That is... until I tried the mini-games. During my play of the "challenge" slider, I noticed the pieces would hesitate quite a bit before responding to my button presses. At one point, one of the pieces even left the screen, something I don't think was intended.
All in all, it's a great addition to the Shift franchise (since you're charging for certain versions), albeit different in a few aspects, including graphics. I just wish that the lag would stop long enough for me to beat level 2-9 without dying to spikes placed below a turn panel.
