I love that this project exists and I truly hope you complete it. I'm doing something similar in remaking Zelda 2 so I know the struggle of translating 2d to top down (and making a github was a really damn good idea, wtf is wrong with me) but if I can offer any support in future i'll be sure to let you know <3"
I REALLY wanna play this haha
Hello there! I'm glad to hear that! I'm not actively working on it at the moment as my attention has been drawn towards other non-game related projects but I do intend to complete it at some point. Zelda's Adventure was a damn good idea that suffered at the hands of poor game developers and console limitations, so translating it into a real Zelda-like game is the most merciful thing anybody could do. Hell, I know that if I wasn't the one working on this project I myself would want to play this game.
If you have any assistance you'd want to offer, I'm always open! And if you do want to play what's there so far, you can download the files from the GitHub and open them in Solarus.
