Description

Welcome to the official UMS group! -- I DO NOT WORK ON THIS ANYMORE, GO PLAY SOULBOUND ON MY MAIN GROUP -- this game started off as a remake of Undertale multiverse theory by dukk_c but ended up being changed drastically so its pretty much its own thing now.

Written by the group; not a statement by this register.

Membership history

Growth

2 measurements spanning 5 days, net -1. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 1,452–1,453 and does not start at zero.
