In an ancient Mayan temple sits a boulder, dutifully guarding the great wealth stored inside and patiently awaiting the day that someone might dare to take it.

In this mobile phone game you play a large boulder, hell bent on squashing the adventurers who've pilfered mayan gold.

You were chosen by the temple builders millenia ago and imbued with powerful magic, giving you unique abilities and all consuming drive to protect the treasure

Each level is procedurally generated but set at a specific difficulty level. So levels increase in difficulty as you play but are always unique. The goal in each level would be to catch up to the thief, who has gotten a large head start and crush them into a fine paste.

The player is able to swipe the boulder left and right to avoid obstacles that slow you down and collide with ones that speed you up. Game ending chasms would have jumps that the boulder must roll over in order to make it across.

As the adventurer flees, they gradually drop their loot, leaving gold coins behind for the boulder to roll over and pick up. Picking up a certain number of these coins would grant the boulder a morality boost and give a randomised power up.
