I didn't make these myself, but here are the maps for all the games areas. They're marked with key items (including quest items), hidden chests, certain costumes, and gacha coins.
Considering updating them with item/clothing merchant locations, quest NPC locations, boss rooms, heart/magic upgrades, permanent upgrades, and summoning stone locations for when the patch fixes the issue.
Crunched some numbers in terms of money grinding as well. To 100% the game (i.e. buy all costumes and equipables) you need somewhere in the ballpark of 15k gold. You can use cheat engine to pump up your numbers. I know enemies drop more cash on death in the 1.3 patch, so hopefully there isn't a need to grind then.
