The last two DS Zeldas were basically begging to be cloned by someone with even an iota of common sense - they had fun dungeon/town sections spoiled by incredibly tedious overworlds that basically ruin the games (especially in the train one, I have no idea what they were thinking). Literally all you'd need to do to fix it is to yank out the boat/train sections and chuck in an overworld.

I started on one for iOS a while back but got bogged down with A) trying to roguelike it up B) models/animation, which I can't make nor afford to commission.

Wouldn't be too terribly difficult. I'd make one and keep it simple. Was thinking of doing it on Android possibly.
