Here's a screenshot of the game:

You move the blue cannon left and right with your mouse. You can shoot a balloon by clicking. The balloon will float upwards, and will pop if it hits a square wall, a spike or an alien ship.

The triangular walls make the balloon slide diagonally. The objective is to defeat the alien ships without running out of balloons. The spikes move around in certain patterns, making the game harder.
