'four pages across two screens' - So what you mean by this is the ability to duplicate the manual so that it can show all four pages?
I feel like the multiple page problem can be fixed with illustrations under each attract mode specification
For example:
'Ball always spawn at middle, going towards the top of the Left Paddle' - For this I would put an illustration under this text showing a ball then an arrow pointing towards the top left going above the Left Paddle, with another arrow showing the Left Paddle is going up.
Now for the walking sound effect, I used this free sound asset From Zapsplat . I'll take note of this suggestion but first, I'll see if the footstep doesn't sound right for others too.
Thank you!
