I like Masashi Tanaka's manga Gon (ゴン). There has been a video game adaptation for the Super Famicom and it's exactly the same atmosphere than in the manga. There's no dialog at all, you are a small and pissed off dinosaur jerking around in the jungle, headbutting random animals and that's about it.
