Rumble: The Mad Match is a cancelled fantasy dodge ball game that was in development for the GameBoy Color at Protonic Interactive (also known as Prograph Research) around 2000. The italian team cooked up a game that looks very reminiscent of Neo Geo classic Windjammers only with six (plus one hidden) strange fantasy creatures as players. The goal was to score more points than your opponent by throwing the ball behind him even with the use of special moves.
Here what Massimiliano Calamai, Prograph Research developer at the time, recalls about the project:
Rumble was designed and completed in a few months in a space of time secondary to the priority projects of Prograph.
Game Boy Color market was already down sharply and we found no publisher interested in publishing; unfortunately at that time you had to have an interesting license or else paradoxically , even if the product was complete, it was not worth to be published due to the high cartridge production costs.
The game was never released despite being complete.
