Thank you for taking the time to play and write such detailed feedback!
I'm glad you noticed things like the input remapping, controller support, and mouse calibration.
The town navigation, tutorial progression, shop flow, dialogue readability during combat, and ESC behavior are all things that could be improved. Well, the browser makes the escape key hard, but I can make it more obvious that middle mouse button is the default "menu" key so you can play the entire game mouse-only if you like.
The comments about combat are helpful. I'll add a separate keybind for sheathing/unsheathing the weapon from abilities.
The next update should have nicer looking terrain and updated sound/music.
Thanks for the heads up on the speech bubbles. I can make the contrast a bit better, all you missed was that the trainer and beast master give tips and strategies based on current equipment and pet.
The VFX setting mainly effects max number of decals light footsteps and blood (I'll have to separate these, I agree that blood is higher priority lol), max number of flavor physics objects like limbs and fragments, particle lifetime and number, shadows on/off, lights on/off. Also it scales the intensity of the prediction/smoothing function when connected as a client.
