Eh, I think Duck Hunt should be just Duck Hunt. It doesn't make sense to turn it into an adventure game. It even goes against the name too. It just feels like making a whole new game and just slap on a completely unfitting old IP onto it for the sake of it. (And no, Kid Icarus Uprising does not count, the direction it had was very fitting)
Ice Climbers on the other hand... I think that can definitely work!
For real a Zelda 1 remake is really need the game has aged terribly
As long as the game keeps the whole "you have to wander around to find the next dungeon", I'll be okay with a remake.
I think it's one of the game's charms, I even drew out a map as I played it and I thought that was a neat experience. My main issue is just how enemies tends to be cheap. **** Dungeon 6.
Honestly, they don't even need to completely rehaul the game. Maybe even keep the same graphics, but make the controls less stiff and have it so you spawn with all of your hearts after death + adjust the enemy difficulty balance.
I honestly think the game is very cool, it just has some weird difficulty flaws and some gameplay oversights.
