OK, me again.

This time I've got something really, really, really difficult, and I don't think anybody can help me, but I'll try anyway.

The game I'm looking for was some kind of Puzzle/Action-Mix. You controlled a guy in different episodes and moved from room to room solving puzzles and defeating enemys.
As said the game was released in different episodes and they were some kind of Shareware. Whenever you get to the last level of each episode, the game asks you for a code, you had to buy. If you don't have that code, you couldn't finish the game.

There were pretty much episodes of it, I think.

The downside: The game was german, and I don't know if an english version was ever released.

Sadly, I can't remember any names.

Hope someone can help me out.
