Cuthenum

A quiet precision game about cutting a photo or a shape to a moving number. No timer, no lives. One blade, six creatures, and a fresh ratio every lock.

Main features：
Play Slice: Random creature + random 1–100% target. Drag or tilt the blade, then lock.
Creature Hex: Six original animals with different mass layouts and personal bests.
Daily Rift: One seeded creature and ratio for the calendar day. One lock.
Precision Lab: Unlimited practice with live left/right mass readouts.
Cut Chronicle: History graded to the hundredth of a percent.
Sigils: Trophies for sharp eyes, hex collection, streaks, and edge-ratio hunts.
Playbook & Tuning: Rules, grade table, haptics, live ghost, and data reset.

Each cut asks a new question, and the animals lie to the eye on purpose. You get a honest delta, a grade, and a reason to come back tomorrow for the same rift everyone else is hunting.
