You have now access to hints and gallery for episode 2 to 4. Just click the icon in the lower left corner.
If you want to replay the game and want to have access to hints you’ll need to delete your persistent file from game folder \game\saves. You also need to remove persistent file form c:\\Users\User\AppData\Roaming\Renpy\My best friends daughter.

Never use TAB or any other skipping function – you’ll never be able to succeed. Keep an eye on the upper left corner when you play. Once an icon appears – you need to decide if you’ll follow the person/fly or just continue.

If you go to the Toolbox and select ‘Game mechanics’ you’ll be able to replay the instructions and how the level of shy, love and horny works.
The gallery and hint system is in its very early state. Bugs may/will occur however It's under constantly improvement.
