I have to say, Do No Evil was a fun quest. I really enjoyed it. The puzzles were mildly challenging, but not game-stoppers. The boss combats were fun, and again, mildly challenging, but never a threat. Monique did have to stop in mid-fight with one of the bosses, but only because she was wearing the wrong equipment. Once she picked more effective gear (specifically, she thought a Magic Shortbow would be sufficient, and of course, that means no shield. When she got her Rune Crossbow and Dragonfire Shield, she had no problem.) The sound effects during one fight in particular were very effective... kind of a persistent beat like a big kettle drum, made me feel like I was in a very dangerous situation. Really added to the ambience.
The puzzles were pretty good. I enjoyed the banana puzzle, even though Monique beat it much faster than I did. I tend to do better at combat, she excels in observation and puzzle-solving. The Choc-Ice thing could have been worse, but if your spellcasting level is high enough, it's not really a problem. There was one point that I needed to switch back to human on Ape Atoll, and nowhere safe in sight. But if you walk into one of the little huts, and go up the ladder, you can change to human, cast your spell on the choc ice, and change back to ape, all with no interruptions from the overzealous guards.

I enjoyed building my own little ape outpost, and setting up the carpet ride. Since Monique and I do the penguins every week, I think that will give us a great access point to help find the desert penguins.
The story was an enjoyable one, and I really sympathized with Apmeken. What happened to her was deliciously horrible, and I felt good about being able to restore her to her proper self.
The rewards were nice; I prefer high-level weapons or armor, like Korasi's Sword from "The Void Stares Back". But still, the Cramulet is cool because it combines several unique amulets and saves bank space. The experience rewards were very good. I liked the amounts.

This has definitely been one of my favorite quests. Not too hard, not too easy, and the puzzles were reasonable. (I usually hate puzzles!) Below are some images taken during the quest. Nothing thorough, just an occasional snapshot to help show the mood of the quest.
