Huh. This scenario certainly was short. It was made in twenty-four hours, though, so that might explain it. It actually explains all of the flaws in the scenario.
Turn That Frown Upside Down is a silly, silly scenario. In fact, it is so silly that it is bordering on just being plain stupid. How so? Allow this intro screen from the scenario speak for itself. Gaze at the face of the enemy!
Yeah, that is what you fight. Your allies are the polar opposites of the enemy and they really have no motive for killing each other and I did not know why I should have cared. But then again, TTFUD should definitely not be analyzed too deeply because, again, it is just plain silly.
The twenty-four hour limit shows in the quality of town design. To put it bluntly, it is quite sloppy. There is a room, for example, with about a dozen empty chests. The outdoors are not an improvement and the player should not bother exploring. Everything is so very empty.
The fights are all very easy, mainly because your allies are incredibly over-powered. The boss fight tries to make up for this by having the player fight something with ten times more hit points than what you've seen before. In the end, the fighting is pretty much the entire point of the scenario and I do not think that is enough. Still, the goofy premise itself was enough to make me finish the scenario. Some might frown upon the silliness, but it did make me smile.
