My review of the game:
Storyline
Well, most of it, I loved. There were lots of plot twists and suspense (I spent most of the game thinking that an Ice Troll was following me, because I didn't see the Jeeboo well, and Guggenheimer was one of the last wizards I rescued) and most of the plot came together in the end. As polished as it was, some parts, like the Z-Bots conspiring with the Grynklers, stealing the flow of the Jeeboo (why not just kill the Jeeboo?), turning chompers into machines, and setting up stations on Uo, were never explained and felt too random. And everyone said Grennfleagel was there at the beginning when you first visited the Planet Of The Z-Bots, and got blasted to Jaava, but he wasn't there. This wasn't just a "getting technical" little joke, it was a major part of the storyline that confused me.
Visuals/Graphics
Amazing. Just Wow. They blew my mind. Each place was given a distinct style, and you really could tell that you were visiting different planers. You really could. My only two gripes were the new transporter style (I would've liked it to have been on the transporters in the Planet Of The Z-Bots, but nowhere else) and that Barren was a bit too dark; I would've liked it better if it had been more light, like sand, so it would've really felt like a massive desert.
Gameplay/Level Design
Well, the game
was very hard, I'll say. It started easy and had a good learning curve, which I appreciated. New elements were introduced and thoroughly explained (except Rainbow Bubbles, which I didn't appreciate). It had a great selection of puzzles, but I agree with everyone who says that there's a limit to alternate solutions. Some of them (like my magic choice to Rescue Mission B), were fun to use. Others, like several solutions to Suspicious Silence, were too much. If there's a level where the player should have to use every magic spell (or every key, etc.), alternate solutions where you don't use every spell should be dealt with. My biggest complaint about POTZ was that certain elements were only used in specific places, and it was possible to skip levels introducing certain elements. Magic probably should've been required to learn at the academy, so they wouldn't only be usable in a certain planet (this would have made random combinations possible like Flash on Jaava, Grow on Barren, and most importantly, Brr on Qwertyx.) But other than that, the puzzles were great. "Escape!" took me days to solve, and the feeling of pride at the end was worth it.
Audiovisuals
Well, I loved some of the new music tracks, and the new command that can be used to adjust the music is also pretty cool.
In Conclusion
Overall, I'd give it a pretty high rating, but not a perfect one. I definitely love it!
