Regarding the first point, I only know of one solution: install a program that automatically renames each autosave. After the game, load each save and see what it did and how. If you are experienced enough, you will find almost any cheat (you can even guess that the person reviewed the map).
Regarding the rules, it's up to you. Here, most people play according to our (World of Xeen) rules, but there are many players who came to us from the portal, and their rules are slightly different from ours. There are also players who play according to the Chaos League rules, but I haven't seen them in a long time, and I don't know the rules myself.
Regarding the Gorportal, check the rules. If there is nothing in the restrictions, then it is allowed.
Но поскольку я нищий,
у меня лишь есть мечты.
Я разостлал свои мечты пред вашими ногами.
Ступайте бережно, ибо вы ступаете по моим мечтам.
