Having played (And won) this games, four things stick in my mind:
The author was not exactly fluent with the English language when they made this, however almost all of the dialog is understandable... after a fashon.
Some of the objects have sloppy programming, including lack of approprate #lock commands, so touching something out of order can block any progress in the game.
In some cases the board entrances aren't lined up, or just aren't connected, or a vital door/passage object isn't programmed correctly, blocking any further progress in the game. This requires use of UnLockPRO.
Finally, the game is a well thought out "Adventure" with objects, inventories, RPG battles, etc. Note also in a few rooms the "extention" of the blue panel to the right of the gameboard. THAT I find highly helpful and inventive.
I'll give it a 4.5 despite the hacking required.
