I was thinking it'd probably be helpful if the maps showed which pipes you can go down (some are obvious, but some aren't, for example Pumpkin Zone 3 and Pumpkin Zone 4), and also which enemies do NOT appear in "Easy Mode".
No one agrees?
You could try... you know... actually doing it yourself?
Not everyone makes maps with the intention of providing a walkthrough. Aesthetics may be more important.
