So I've tried to get the hardest achievement (I Have it) which I know that you have to fail all 7 notebooks in grand opening without cheating and for some reason I never gotten this achievement even though I did it without cheating. Have I done it wrong? Does this have to do with the math machine because I've gotten rid of all the number balloons and used the correct answer since it's the only way to collect a notebook.
I've just beaten it 2 times and I still never get this achievement which felt like I've wasted so much attempt for nothing.
I'm not sure whether it's a bug or am I doing it wrong.
Anyways, thank you for reading it! I'll try again sometimes soon
Although I have a feeling the obtaining of this achievement is fake but we'll see
