I'm glad the Vive wand support worked well! I have a soft spot in my heart for Vive wands - they're so much more beginner friendly than the other controllers, are ambidextrous, and the touchpad is a blank canvas of usage options for developers.
As for cuteness value, I think even adding the legs might have been a mistake, but I wanted to honor the "bugs" theme and not go too "worm". I kept trying to decide between cute and creepy, but creepy became too creepy and made my skin crawl. Imagine the larva moving 4 times as fast, and being a lot more squirmy and chaotic, and with longer centipede style legs splayed out to the side - it was too triggering.
Also, I found that slower movement helped physics performance on the Meta Quest 3, which is pretty much limited to a mobile device CPU/GPU and much more limited than a desktop PC.
