desktop, tablet, mobile.

### Can friends play together?

Single player against AI rivals. No human multiplayer or online multiplayer.

### What are the controls?

Move with WASD/arrows or the bottom-right proportional touch joystick. Phone portrait-first, landscape supported. Swallow objects by moving under them and allowing them to tip and fall completely; objects keep their scale. A 150-second race has seven local AI rivals and three decision difficulties, plus solo untimed free roam and twelve sequential challenges across four seeded city layouts. Larger holes need 1.15x diameter and at least 30% of the smaller hole’s area overlapped continuously for 0.25 seconds; full coverage is not required. Respawn after 3 seconds with 85% mass retained and 3 seconds protection; transferred mass is conserved. Cosmetic colours do not change rules. P/Esc pauses, M sound. Local current-run resume and AES-GCM JSON backup with preview/confirmation; no account or cloud save. Background pauses everything. Every visit starts muted and follows portal URL language.

### Is it free, and does it require an account or download?

Free browser game, with no sign-up or installation.

### How do language and sound work?

English and Simplified Chinese. The portal passes the selected language; English is the default and games have no separate language selector. Every load starts muted; sound requires explicit opt-in.
