I don't know if there is anything you can do about it given the engine - but the web-app is a little difficult to work with as a user. Being fully rendered as a canvas, my password manager can't work with the username/password boxes, and I can't even right click to paste on the password field. I'm reluctant to sign up to things I can't use a password manager for!
Might be worth considering having some of the initial register/login stuff being more normal HTML/CSS, then moving to the canvas once logged in.
