Been meaning to leave this feedback here for a while. I see the twiddler 4 is already underway now so maybe this is too late, but here it is anyway. Two two things I think would improve the Twiddler 3 for me the most are:
@sam1am Thanks for the input!
interesting design idea. We made a decision to keep the design universal instead of going with a Left and Right hand version. The 1st thought is to get a RH version if you are right hand dominant and this is usually the wrong hand.
We are using the PixArt OFN for the mouse so your wish has been granted.
How about using the twiddler like the Logitech MX Air, which was like the light gun we had for Duck Hunt on Nintendo. That's way easier than a joystick and sometimes preferable to a pad, at least until we get glasses with eye tracking.
