Game Modes

• Normal Expedition: The classic experience. Dig until your rig fails, then return to the shop to upgrade and try again. The goal is to reach a new maximum depth.
• Time Attack: A frantic 5-minute session. Dig as many times as you can within the time limit. You can upgrade between digs. Your final score is the total from all runs combined.
• Sprint Descent: Race against a personal timer. Pass through checkpoint gates to add more time, but beware—the clock speeds up as you go! Rig failures only send you to the shop; only the timer can end your run.
