It is SUPER challenging, requiring twice the coordination of pong, AND it incorporates the elements of fire and ice to make it even more difficult.

It's $1 to download, but be honest, you've spent $1 on worse things, and if you love arcade games, this is worth it.

This game was actually created by my instructor at the college I go to, through a company that he just formed together recently. I'd like to help advertise and get the word out some more.
