About the manual, what I had in mind was something like two pages shown on one screen, or four pages across two screens. For example, I initially thought page 8 was supposed to come after page 9, which confused me for a little while.
Page 10 was also a bit harder for me to understand without a supporting image, so I think keeping each game's instructions visually grouped together could help a lot. That said, I can also see how adding more illustrations might make the manual easier to read overall, even if it means having more pages.
As for the walking sound effect — yes, that's basically what I meant. I can tell the timing is matched to the walking animation, but the sound itself doesn't quite read as footsteps to me. It might be a little too heavy or impactful, though I'm not completely sure how to describe it.
Thanks for asking!
