I actually thought the same about the cartoony appearance of Monster Boy at first. However, I've played the Wonderboy games it's based on, so I knew what to expect as far as game play. It's precise action platforming with a hint of RPG and adventure as well. The story is decent, and somewhat humorous, and as cartoony as it is, it's actually quite amusing. After playing for a bit, you forget about that aspect, and just start enjoying it for what it is. I'm sure it's not everyone's style, but it's absolutely flawless for what it is, and what it's based on.
