Zooming out would help but for some reason neither Safari nor Chrome provides controls for that (or is it only my ipad? it's very old). You can try this non-itch version of the generator: https://watabou.github.io/one-page-dungeon/. Please note that this version is WIP and it contains some undebugged features.
Zooming out works on other pages in my chrome application on my I pad pro.
The new link works well! Shame that I can pop out the menu If I hold down my finger on some text on screen but every finger stroke creates a new dungeon...So If I can't open the menu without switching dungeon.
Any way to add a lock button or a solution? :)
