Burrow Balls: drill gun and glass balls
This is one of the pumping games: you aim a drill cannon and send glass balls into the rock. Each broken stone yields gems, and glowing veins pay seven times as much, so destruction immediately feeds upgrades.
How to start the first pass
- Drag left and right to aim the gun.
- The balls fly on their own as long as there is enough fuel.
- New upgrades are unlocked as you go deeper.
What does the workshop buy for gems?
In the workshop, you spend gems on faster shooting, heavy balls, explosive and acid balls, and double shot. Their physics is important because the balls ricochet, chip and break the stone. You still aim the drill cannon at the rock, just like in Cannon Balls.
New biomes and a new starting point
Each new biome becomes a new starting point as you get deeper. So you go through 30 drawn biomes in 6 worlds and go to the Heart of the world 2.4 km down. Each new place reveals the next layer of rock. When the rock gets too hard, you trigger Rebirth and start over. Fossils permanently enhance every ball hit. After that, you go deeper again and unlock new improvements.
