I get this and Slime World confused at times.
Jim Power is 100% a "Euro" game, looks like it was ripped out of an Amiga. The game backgrounds look stellar but that jump mechanic (glitch?) is annoying. I would say the hit box is too big, but I already mentioned it's a European game. Music rocks. Only 5 levels as far as I know. Invincibility cheat was the only way I could see any level past 1
I wonder why the publisher decided to port this game (and the other Micro World releases) out of all the possible computer games that were out there? Games like Baby Jo, Davis Cup Tennis, Kickboxing, Builderland and Slime, all must have been super cheap to acquire.
