YMMV / Kao the Kangaroo

• Game-Breaker: The GBA games have one in the form of the butt bounce move, which, as the name implies, lets you bounce off the top of enemies while dealing damage. What the game doesn't tell you is that you can adjust yourself after every bounce. By itself it isn't much, since you can kill almost every enemy in one hit; however, it's the boss battles where this comes out to shine: every single one of the bosses has a large frame, an unfairly large health bar, and does a ton of damage. Almost every single boss also has some sort of platforms that allow you to get to their head level. As a result, killing bosses really just comes down to getting on one of these platforms, jumping over their heads, using the butt bounce when they get close, and then slightly tapping the d-pad so that you repeatedly bounce on their heads. This absolutely trivializes the boss battles, as none of the bosses have any attacks that go over their heads at all, and even though some bosses ensure you're going to fall off after a few bounces, it's incredibly easy to just get back on that platform and start again. The only exception should be the Genie, who has no platforms in his arena, but since he has a lamp he periodically goes in and out of, all you have to do is wait until he goes back into his lamp, look for the wisps of smoke, and try bouncing on that, which instantly places you atop his head while still bouncing on it; and because of the nature of his AI, he'll literally just stand there motionless if you do so, meaning most of the time you can deplete his entire health bar in one go.
• It's Short, So It Sucks!: The third game gets this compared to the first two, with fewer levels than the second game and not as much to do.
• Polished Port: While the graphics and framerate had to be downgraded, Kao Challengers, a port of Round 2 for the PSP, still runs reasonably well, and adds a multiplayer mode in addition to keeping the content of the console versions.
• Scrappy Mechanic: The first game had a few of these, such as making you put up your own checkpoints (which the game never tells you about, let alone that there even are checkpoints; you have to consult the manual or look it up online to find out), and in the vehicle segments, if you even hit an object, it's a One-Hit Kill. Thankfully, these issues were fixed in the sequels.
• Sequel Displacement: The series as a whole is pretty obscure, but most who did know of it played or at least heard of Round 2; there were some who didn't even realize it was a sequel.
• Surprisingly Improved Sequel: Even those who played the first game will admit the sequel improved many things from it, from having a bigger scope to a more open feeling, and some minor annoyances from the original being fixed as well.
