Yet another homebrew hit has surfaced on the Sega Dreamcast. The team behind the incredibly addictive homebrew driver Rush Rush Rally Racing have ported Hotpengu's retro-flavoured Flash platformer, Polyko's Super Jelly Bean Quest in the Sketchbook of Illusion, to the Sega Dreamcast. Best of all, the game can be downloaded for free.
If you haven't already played this homebrew mouthful, you're placed in control of an artist by the name of Polyko, who has been transported into a world of his own creations. It's up to you to collect the 31 jellybeans scattered around the world, in the hope of transporting Polyko back home.
Senile Team of Rush Rush Rally Racing fame have released a downloadable Sega Dreamcast ISO on their website, ready to be burnt onto a CD and played on the original hardware.
