Petarimubu (ペタリムーブ) is a quirky little physics-based action game where you move your four legs independently to traverse a narrow tunnel system without letting your body touch a surface.

It's good. Doesn't work on mobiles though, which is a shame as it would be perfect for a touchscreen. That's probably why there are very few comments. Also, it's all in Chinese.
