The Tower of Time pack includes a new level that contains an interesting stop-time mechanic, as well as the air-type character, Pop Thorn. Like past Adventure Packs, Tower of Time also comes with two magic items, the Battle Hammer and the Sky Diamond.
The new level itself has you trying to stop a strange new villian from taking over a clock tower that seems to have control over time. You will have to take down this strange steam-punk chicken by going into his nests found throughout the level and collecting the cogs that will fix the Tower of Time. The level contains switches that allow you to temporarily stop time, which adds a nice sepia tone filter over the screen, and lets you waylay oppoenents without fear of retribution. Well, that is, until a new type of Spell Punk shows up that can undo the stopped-time effect. There are also quite a few interesting environment puzzles that come along with the ability to stop time. There are quite a few fast-moving platforms that you must get across, and the only way to do that is to stop time when they are positioned so you can get across. Similarly, there are doors and other obstacles that all require good timing, even with the paused time.
As for those new Spell Punk enemies, they become truly annoying when facing off another new enemy, a golem that is impervious to your attacks unless time is stopped. When you first encounter this new enemy, it isn't long before you figure out the trick to its defeat, but later encounters involve the annoying Spell Punks that don't let your paused-time last very long. Just like any other time a Spell Punk shows up, the best strategy is to take them out before trying to seriously damage the other enemies on the field that they augment.
Of course, the level all leads up to your encounter with the level's main enemy, Cluck. You will face this cuckoo in the tower's upper levels, but by the time you get to him, you will have a full understanding of the time-stopping mechanic and the best way to use it against your enemy.
