Hmmm your version of the game seems to be a bit buggy. The tips aren't supposed to be empty, and your mom is supposed to show up on the balcony after you slipped the diary under the door. Are you playing version eng1.2 ?
I played version 1.1
Thank you for playing.
If you send us mail, you can get txt files of Tips.Or, if you copy and paste your savedata.bin, you can read Tips in new version.
Downloading 1.2. I'll play it again. :)
