Hey I am building a simulation game and am using quests map but its very buggy. I was wondering if there is a desktop library I can add or a way to make the map better.

Map every room on the same level, no odd shaped rooms, no overlapping rooms.

Have you read the docs? It does address some of the issues.

Most of the issues with the map have some kind of workaround.

Alternatively, you could include map images in the frame, or in a sidebar pane.
There's already an option for a room to have a picture which is displayed as long as the player remains there; you could use that with an image of the map for each location; or even have many rooms share one map and add some javascript to move a "you are here" pointer around on it.

I did think about changing the frontend part of the map system, taking Paper.js out of the equation because it isn't really necessary; but that would be a major overhaul.

Thank you, it is sad that the map can be a bit buggy but I think I have the issues solved.
