From what I've seen in your update it looks good. If I knew what I was looking for I could report better, but for now I can't play the first or second island again.
Maybe it's just me, but I've always liked using the editors where you would go to a sign or an obelisk to cheat. If someone needed items, skills, spells, experience, money…. they would go through a series of menus to get what they want. That way there is an option to receive level appropriate equipment, rather than the most powerful items in the game after opening the very first door.
Though Alwan joining you gives you maxed stats, very nice if you want to play as a God. This makes it so you can't take Alwan with you without heavily cheating. Placing these options in an obelisk or the testing ground would give the option of playing the game without cheating, but still using your scripts.
Maybe an option to raise stats by 1,2,4,5,10,30 would make it so one could cheat a little or a lot. I hope I wrote that without being offensive.
