Of hex editors, cursed items and negative effects
There are quite some hidden bugs in Ambermoon which never would have been noticed if it wasn't for the Ambermoon Advanced project. The cursed items feature is very cool in my opinion, but as there is only one single item in the game which is cursed, it left me with the impression of wasted potential.
Of Data Tricks, Lizard Heads and Smugglers
There is no doubt: Ambermoon is huge! Not only the world but also the things you can do. But there are many little details as well. Perhaps some of them are only noticed in the second or third playthrough, if ever.
Of Savegames, Redundant Data and Baywatch
Ambermoon savegames have a big potential for errors: They store redundant data. For example they store all the items, gold and food a character carries but in addition they also store the total weight.
