Hello and thank you for your kind words ^^

ComeCloser supports trackers for both the virtual penis and the replication feature. You can have one tracker for each, in addition to your hand, or any other combination. The game is only tester with Vive Trackers but should work with any tracker, as long as SteamVR recognizes it. Sadly I can't tell if Pico Motion trackers in particular are supported, since I haven't tested them myself and haven't had any feedback about it in the community yet. Maybe ask the question on our Discord server?
Have fun with ComeCloser!
