Sorry if I did'nt answer you first. (time to translate your post and my humble answer)

BTW, it's great that you're making an "oldies-flavoured" game, but remember that there's things in the old games that disappeared in modern design - and for a good reason.
I agree - oh my god I agree. I'm not a nostalgic 'by itself' - But if I'm creating a game like that it's mainly because there a kind of original fix that I was unable to find anywhere in adventure game since MM and Zak.
I see you've implemented mazes - just as long as they're easily mappable. I see you've implemented a huge gameworld - just as long as it's not a lot of going to and fro and to and fro and fro and to again with the player having barely a clue of what to do at any given time due to the sheer amount of possibilities.
I know that mazes have a very bad reputation inside the gaming community. : (even the creator of Zak once said that if he had the choice, There will be no maze at all!).
I disagree.
Mazes can give a feeling of exploration and discovery, that puzzles or cutscenes won't do.
BTW, If you ever have finish Zak ... do you remember the yellow crystal ?
I see you've emulated the original Zack - just as long as you don't include a walking dead (please GOD no walking deads), and don't have the "need money to travel" limitation (I know, I know, it was a puzzle, but it's one of the reasons that got me to give up on Zack. I want to explore, I don't want to be limited by something like money).
I appreciate that someone share my interest for the exploration factor in games' but:
1- Money should matter : In this case, less than in Zak1. Possibilities to gain money are huges. I don't want to spoil something but My 2nd screenie can give you a clue on the way Zak will earn his cash.
2 - Yes you can die. Not of a "Leisure Suit Larry Dead" - just an early LucasArts one. Just a matter of coherence. Or a char say 'I don't wanna' or Yes, he can push the red button.
Out of curiosity, how many player characters will there be? Will they be swictheable? And is knowledge of Zack 1 necessary for playing and enjoying your game?
Officially there is olny 1 player character (telling more will be a spoiler...) But I did type cXXX.setasplayer a couple of time in the main script
Needed knowledge of Z1 : It's hard from my POV to set an honest answer. But, at, the best as I can, It won't. Same athmosphere, same main characters, but not more.
Looks great, absolutely great. 100% old-school, which might not be *everyone's* cup of they, but hey, we're a bunch of nostalgic folks, ain't we? 
YEAH!
Thank for your nice comment
