Dive underground and collect treasure! Use the Left/Right Arrows or A/D to move and press SPACE, C, or P to jump. When you see an exclamation point, press X or O to interact.

There are 300 pieces of loot to collect. You can find loot from opening chests. Once you've amassed a good amount of loot, return to the blue chest to store it.

Keep an eye on your hunger at the top of the screen! The more you explore, the hungrier you get. If you reach 100% hunger, you'll be too tired to explore and you'll lose all the loot you're carrying! Grab some snacks along your journey to eat. Each snack you eat recovers 5% of your hunger. Don't eat too much too fast, or you'll slow down!

Avoid enemies and other obstacles like spikes and flames! If you get hit, you will get hungrier. Collect sticks of dynamite to use against your enemies.

While you don't need keys to unlock chests, you will need them to unlock gates. Find the key that matches the color of the gate to unlock it.

You can swim underground, but don't stay underwater for too long! Keep an eye on your oxygen meter at the top of the screen. If you lose all your oxygen, you'll pass out and lose your loot!
