Thank you for reporting, we'll look into it! What operating system are you running? Does the web version work? Until we find the issue, we recommend using the web version: it should work the same as the desktop version, minus the issue (hopefully).
Hello, sorry for the wait! We weren't able to replicate the bug, but we've added an optional fix for it, toggleable in the options menu. If you find it hard to navigate there, you can add it directly to the game configuration:
Go to "C:\Users\<your PC username>\AppData\Roaming\Godot\app_userdata\RitualBound", and create a plain text file there called config.json. Add the following text to it, save, and it'll work.
{"fix_mouse":true}
