- The page says leaderboard scores are checked by replaying each player's jumps on the server.
Field notes
The controls are deliberately spare: jump with a tap, Space, or the up arrow, and hold to jump higher. Hazards escalate from flying invoices and software errors to cake bombs; the page says reaching the guest list adds full hearts, 3,900 points, and an invited tag. It also describes scoreboards for four time spans and says scores are verified by replaying jumps on the server.
