[TOMT] Old side scroller game involving ninjas.

From what I remember, you played as a ninja-esque guy with up to 4 players. Side scroller, and you could all play on the same keyboard. The "ninjas" had different types, so a frost guy, fire guy, sword guy, etc. It was essentially just moving from one zone to the next beating up hordes of enemies. The file was relatively small, it could've been a flash game, but I don't remember. I know that I downloaded it to install on multiple computers. I remember playing it about 8-10 years ago, it had LAN support as well.
