纯逻辑类，还是有一大半会的。

A short but very sweet platformer with inventive puzzle design that really gets you thinking about the whole map. I love that the progression is more knowledge based than item based. I wish there were more metroidvanias like this!

非常惊人完美的解密游戏！ 从开始的慢慢探索到后面知识的闭环，一步步深入带来的感觉和当时玩闰月之年的感觉相当。 尤其是破坏心脏后返程的路途简直是一场完美的实践。 不过感觉这个游戏主线还是太仁慈了，隐藏真是牛鬼蛇神，惊为天人。 这个隐藏简直是把这个游戏的可能性拓宽了太多太多，令人震撼。 总而言之是一部非常有趣值得一品的佳作。

Great game that makes full use of it's basic controls. There is an interesting use of duplicate puzzles as a teaching tool for alternative solutions. The game is short, but feels like the perfect length to not overstay it's welcome.

Picked up this game after playing Elechead a while back, which was also a great puzzle-platformer from this developer. Ooo is a short yet incredibly clever and well-designed puzzle platformer that introduces and builds mechanics seamlessly without using any actual text, just through level design. The world is also fun to explore, which branches out in a way that lets you go back and try other puzzles in other paths if you're stuck. Well worth it to anyone who likes puzzle-platformers, this is genuinely one of the best out there.
