It is not necessary to make a donation in order to win.
The first step is to download and play the demo.
Clues are found in the demo, and will lead to a Litecoin wallet's private key.
The last step is to send the Litecoins from the treasure hunt Litecoin wallet to a separate Litecoin wallet that only you own.

The green orbs, timer, and lava have no connection to the treasure hunt. They are meant only to be fun objectives.
