I think it might be a bit too big? I'd leave it as a "console" option for who plays it on a couch with Big Picture, and add a "desktop" smaller version so that it doesn't clutter the view (or maybe even better, add a scalable option).
Yeah, good point! Maybe will add some options to customize the HUD in settings (turn on, off some elements, maybe make HUD variations etc)
In terms of the HUD design itself I was also thinking about trying some kind of minimalistic design where it wont take a lot of attention during gameplay - soon enough I will have something to show in that matter (after Main Menu UI finalization)
