Can you beat all 18 levels?

Hints: - Use the left and right arrow keys to angle your shot. - Plan your shot by pressing the up and down arrow keys. - Press and hold the spacebar to charge your shot, then release to swing. - The fish indicates wind. The first two levels give you a "wind preview", but after that you will need to look at the fish. - Clear the golden ingot to make progress. - Make sure to get the blocks within the grid under the sea.

There are other weird little things going on, but that's all you need to get started. Good luck!
