I like this game! I think it's really well-built. But I encountered some errors, and it's unfortunate.
There were two folders with the same password (MySecrets). The other is the Diary folder and the other folder with the same password was found within the "core" folder (one of the three folders, at least). It was a folder titled "Sorry."
When I opened the Diary folder, there was also a dead icon I couldn't open. It was gray and looked small compared to the usual appearance of a note icon. Meanwhile, in the Sorry folder, I found an awkwardly placed note document and I think that was supposed to be the dead file.
At the end, I couldn't find the last drive to be installed, despite the fact that all folders have been opened and all remaining drives have been installed, and the game was stuck at the progress of 5/6 drives. Would also like to point out that in the division section, there were times that the division part didn't make sense, at least to me. We're supposed to divide the first number by the second number, right? It was confusing when the first number was 60 and the second number was 3. 60/3 is 20, and I couldn't input a number higher than 10. I just typed the number closest to the solution and it worked, strangely.
There was also an instance that the first number was 3 and the second number was 2. I inputted every number from 1 to 10 and nothing was correct. I even answered 1.5--that wasn't accepted.
Might be just me who was confused though. Nevertheless, thank you for the nice experience. You did great with the graphics and the story.
