I rented this awesome game for the PS2, and I beat it over 7 days of on and off playing. The graphics are VERY good, and the traps and level layout is excellent. No loading times except for the beginning, and the Story itself is actually unique, and quite refreshing.
My favorite was the Waterfalls area, and god... it gets hard. I ended up with 9 time reverse circles, and a health line that went across the screen to the end almost. (You get added health when you enter that magical place that you drink from). Added time-reversing circles are obtained by stabbing the glowing white flashes throughout the levels.
I just wish it was longer, but I unlocked the original PoP game, and that was SO fun too! I even pulled out my old PoP game box and found level codes, and they WORKED!
