I've already written it under the ratings, but here it is to read again to be on the safe side:
Rarely has an action adventure of this kind on the C64 captivated me so much, not least because of the very fair level of difficulty. Graphics & sound are quite simple, but the story, the logical little puzzles and the hints always given by the game captivate you up to the last second. There are also enough energy refill stations so that you never lose interest in it. The idea and implementation of the Automap is very exemplary and helpful. I would wish something like that for many other games on the C64, in which you sometimes look dead and stupid. Here is a small suggestion for improvement: Locked doors could also be marked as such with a corresponding color depending on the security level. The idea of achievements (order of solved puzzles, number of notes found, playing time, etc.) also increases replay value. On the other hand, the fact that the character can only move diagonally or vertically, but not in both directions at the same time, is a bit confusing. It's also a shame that the season was so short. Perhaps some ideas could be implemented here for potential successors without cutting back on the great features of the game. This game is definitely an insider tip and should be played by every C64 owner. 😎👍
