Click inside of the red box and you will get 30 achievements

When you have started level A, click the settings button at the top left corner of the screen and you will be given achievements

At level S, you will come across a stack of red blocks. Despite being useless for the particular level, clicking on those stack of red explosive blocks gets you Boom! achievements

The Heart found in Level 马 (horse, pronounced ma) is another secret achievement. All you have to do is just click on the red explosive box inside the hearts and you can get the achievements

I have not yet encountered a difficult level if they are any levels that you cannot complete, comment down below and i will try to make another section for the particular level.
