What device are you playing on? I’ve had a few issues with that on different platforms but I had thought it was working properly for PCs at least. The web build is actually an after thought because it’s designed to be played locally, but this way is easier for updates.
I've just uploaded a downloadable build which works for Windows: https://patjw.itch.io/recreant/purchase. This version will have saved games and persistent dungeon levels enabled. If there's still an issue with the UI being too small, that might be an issue with your monitor scaling settings - I have the same issue with one workstation which is set up at 2x scaling and I haven't found an easy way to adjust for that automatically within Godot just yet.
