Alright, another request for you all.
This one is another arcade sidescroller. In it, you play as a ninja (two if it's two player) who seems to be a bounty hunter because each boss is displayed on a wanted sign before each level begins. Bosses include a cowboy, a crooked cop, and a football player, each with an appropriately themed level. Attacking is done via throwing weapons, which change upon being picked up. Pick up the same weapon twice, and you'll get an upgraded version. Also, there's a third button that, when pressed, turns your ninja into a sheet of glass. This renders him invincible, but immobile.
Any help would be appreciated.
Edit: I should probably mention that the graphical style is extremely cartoony. Some of it almost looks like something Jim Davis would do/approve of.
Edit: I just found it. It's called
Charlie Ninja (severe AV desynch in that video, but it's all the internet has).
