the classic of all platform games was developed 1983 by the company Broderbund and was one of the games which were first released for homecomputers like the C64 and then as an arcade game.
each level has narrow paths connected with ladders and our player is followed by enemies and has to collect treasures, on his way.
his only defense is that he can shoot a hole in bricks where his opponents fall in or he can fall through.
once he collected all treasures ways appear that make him go to the next level.
i found this very good and accurate remake of Loderunner which brought me by now hours of fun and if i wouldnt have to write that post by now, i still would be playing it.
