Here's the complete map of the old classic game Sorcery.
The map contains all keys and door-links. In fact, this game is all about mapping! I used to play it in 1986 or so, but always ended dying in the water or just getting bored looking for a key. But with the map, things are a lot easier :)
That's probably not the best 80's game (no in-game musics, only 3 types of ennemies...), but it received lots of good reviews when it came out in France. And for those who spent some nights trying and never managed to finish it, it can be fun to finally beat the game :)
The MSX version has the bigger play-area compared to other platforms (50 different screens). The "Bow and Arrow" weapon shoots mainly to the right, be sure to be on the left side of your ennemies to use it efficiently (have a look at the "Weapons" area in the map to check the shoot-pattern).
Enjoy !
