When I use the non-itch version, the dungeon generated and the descriptive notes don't always fit on the screen. Using the itch.io version I was able to use 'CMD' & '+' or 'CMD' & '-' to adjust the browser screen size to zoom in/out to fix the 'fitting on the screen' issue, but not on the non-itch version. There also don't seem to be instructions visible on the iPad view on how to interact with the generator.
Update: to clarify, I have a keyboard with my iPad. It has become my main digital tool (partly because my computer is quite old now).
