Description (written by the developer; not a statement by this register)

This project is over, but there is a game I created that is way better than this game! Come play it: https://www.roblox.com/games/15657458598/ Undertale Mortals is a fighting game where you play as Sans and try to destroy everyone or try to bring utopia. This game is not being worked on. This game is only in the test phase and is very incomplete. NOTE: Do NOT use Krnl, or any other hacking software, play fair and be friendly to everyone.

Growth

Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.

Badge funnel

Test Phase Player · other228 · 0.00% win

How many players have ever earned each badge — a proxy for how far players get before they stop. Steep drop-offs mark where a game loses people. Win rate is the past-day share of players who earned it; categories are assigned by a language model from each badge’s own name and description.
