Heh, supposed debating about artstyles will always be a thing with Zelda games. Some things will never change, I suppose.
In any case, I come down on the side that absolutely LOVES this artstyle and finds it very fitting to the whimsical nature of Link's Awakening. I also love how it kind of reminds me of stuff like Kirby and the Rainbow Curse. It just works for me.
Though on the other hand, I wasn't really feeling that new rendition of Ballad of the Wind Fish, but that's a super minor thing. The game itself looks brilliant. And this version will definitely be more than worth it, if only to finally have a version that's not limited by the Game Boy's very limited number of buttons, causing you to constantly be in and out of the menu to change equipment and stuff and breaking up the pacing in the process. Being more lenient in terms of equipment like modern Zelda games would make the game so, so much better and entirely worth it by itself.
Personal feelings aside though, Link's Awakening is definitely a brilliant, wonderful game that definitely doesn't deserve to be stuck on the Game Boy and I'm definitely excited that this means that a whole bunch more people will get to play through it for the first time and I hope they enjoy it. That too will definitely make it worth it, even if I myself do for some reason end up not liking some of the changes.
