Landstalker has a great vibe and colorful, appealing characters. It doesn't play well, unfortunately, so I quit after the first couple of dungeons. It is also pretty hard not to compare this game to Link to the Past (which came out around the same time), and the comparison is not favorable.

There is a unique isometric perspective that gives it a cool look, but lacks shadows and environmental depth, so navigation is more difficult than it should be.
Combined with imprecise and squirrelly controls, the visuals make it pretty painful to play.

Combat is extremely simplified. You have a single sword swing and enemies simply walk towards you. There isn't much strategy here beyond waiting for them to come into range and slashing them. The strange isometric control also makes it easy to accidentally walk into enemies, which feels pretty bad.

It is an interesting take on a Zelda-like, with with a cool aesthetic and style, but the gameplay falls short. There just isn't a ton here to recommend beyond the novelty of an attempt at an isometric, grid-based Zelda game.
