While the translation isn't the best, it definitely gives us some insight into the game. Some of this is old, and other bits are brand-new. I will list the facts I feel confident with, but link you to the entire page. Huge thanks to Yesubaybee for the heads up!

- 20 stages
- hand-drawn animation
- 1 player
- locations such as jungle ruins, desert, and ocean
- shake the Wiimote for special actions (shake enemies to grab coins, unearth hidden locations, and more)
- some sort of throwing mechanic via Wiimote manipulation
- vehicles such as rockets and submarines, seems that the Wiimote speaker plays a part in vehicles as well
