I just discovered Superpowers and it sounds like a great solution to create HTML 5 games. I was wondering what about UI components ? I know that usually using the DOM is recommended but I'd like to know it there is basic UI component like Button or similar behavior. It would be great to be able to create UI inside the canvas especially when it comes to drag & drop - I already had to manage UI in the DOM with draggable asset from the DOM to the Canvas and it was a real pain in the ass.
if not Button component exist, is it possible to detect/listen mouse event on a specific sprite ?
