Ooooh boy I'm sorry for you if you only ever got to play them on NES.
Yours looks AND plays a hundred times better than the NES versions (controlling them with a controller was absolute trash back in the day, and it's even harder with an emulator and a keyboard). Your game actually seems much closer to my favorite versions, which were on the Commodore 64 . The graphics and animation, like yours, were far superior. There's something to be said for the black and white Mac graphics, too, which looked like pencil sketches. Really good job here, very well done and super nostalgia-inducing.
Very nice. I say either make a game with half as many room screens so you can have a selectable Mac version, or a game where you travel back and forth between realities and your world is the regular color version but you travel to one where everything including the UI becomes Macventure style... because this style needs to be seen.
