Comix Zone/YMMV

Americans Hate Tingle: According to one of the developers, the management Sega of Japan hated the game and said it "embodied everything that was wrong with American culture".
Goddamned Bats: Kreeps are very easy to kill, but get into Goddamned Bats territory when there are Bottomless Pits about, often knocking you in. There is a panel in page 2 of "Welcome to the Temple" where they keep spawning from a hole, and that hole has to be covered if you want to proceed.
- Taken Up to Eleven in the final boss, where the are produced whenever you use the trick to cause massive damage to said boss. Since you need to defeat all of them, it can either kill you after you beat the boss or cause you to get the bad ending if you're too slow.
It's Short, So It Sucks: Its length (only three stages, each with two pages) is among the complaints this game has.
Porting Disaster: Aside from the expected zoomed-in camera (which already caused some problems by making it feel like a traditional platform game), the music of the Game Boy Advance version, despite being composed by the same person who composed the songs for the Sega Genesis/Mega Drive version, sounded very different from the originals.
- The mobile phone port isn't very well-liked either.
That One Boss: Kung-Fung has longer reach than you, and a ranged attack that requires split-second timing to avoid. If you don't know his secret weakness, you're going to need mad skillz to beat him.

"Your kung fu is good!"

Unfortunate Implications: If you get the good ending, Sketch lives happily ever after with Alissa. Sounds nice, but she's a character he drew, there's just something wrong about the idea of a guy literally creating his own girlfriend.
