Drillnaut: Planet Driller

Pilot a drill pod down a shaft through four planets. Hold the joystick toward rock to drill it, and the pod breaks through one cell at a time. Collect copper, silver, gold and crystal ore as you go. Watch three gauges: fuel, hull and heat. Digging and climbing use fuel. Gas pockets damage the hull. Drilling deep builds heat, and an overheated pod stalls until it cools. Every dive ends at the surface base. There you sell your cargo, refuel, repair the hull for free and buy upgrades for six parts: drill, hull, cargo, radiator, fuel tank and thrusters. The tunnel you dig stays open, so each return makes the next dive quicker. Magma pockets, gas pockets and cave voids make every descent a choice between going deeper and getting back up with ore. Reach the core chamber at the bottom of a planet to complete it, and the next planet unlocks. The planets are Grey Rock, Frost Shelf, Red Dune and Ember Core. Each has its own rock colours and its own hazards. If the pod runs out of fuel, overheats or is badly damaged, a Teleport Beacon sends it back to the base with its cargo kept. Beacons are bought in the shop. An optional rewarded ad can offer an emergency teleport once per dive, and another can double one sale. Rewarded offers are always labelled, and you choose whether to watch them. The game contains ads and offers in-app purchases. Interstitial ads appear only when you leave the surface shop, never during a dive. Remove Ads is a one-time purchase that removes interstitial ads; optional rewarded offers remain. Teleport Beacon ×5 is a consumable pack that adds five beacons. The game is for players aged 13 and over. It plays offline. The internet is used only for ads and for purchases through Google Play.
