JB Le Daron is a french Youtube channel I just jumped on. In this fist episode, he is talking about speedrun : finish a game as fast as possible, often seen on other 8bit computers and consoles, but rarely (or never) on Amstrad CPC to my knowing. And it's Barbarian by Palace Software in 1987 which you will see done quickly.
Will you be able to beat the game Barbarian in less than 6 minutes and 12 seconds, the record made by Kukulcan (CPC-Power) ? The speedrun starts at 6 minutes in the video.
