Attempts to bring the Tears of the Kingdom "creative" spirit to 2D, but it does not try any harder than bare minimum. The VAST majority of puzzles are simply "find a way to cross this gap", and the interface for selecting which "echo" to summon is horrible, which further encourages you to use Table, Crate, and Bed combos for nearly everything rather than spend so much time in that stupid horizontal list.
On top of that, combat is agonizing. Your summoned monster AI is terrible. You drop down a moblin and it stands there for about 3 seconds before even doing something. Slimes do 1/2 a heart of damage and take FIVE SECONDS to charge up an attack. Nearly all your summons give up on fighting halfway through, or die instantly, or get stuck in corners. Many of your summoned monsters do really low damage, resulting in maybe 5-10+ hits to kill enemies, with most of your echo's time spent standing around doing nothing. I wish I was joking, but its true. Monster echoes should have been more "spell" like, where they do an instant, unique attack/effect and then disappear after some time. The only "cool" thing I've ever done with summons is block a flaming keese barrage using water slimes--because the water slimes dont actually do anything, so they acted like a "wall of water" spell, which is what this game never does.
There are a few echoes that are extremely overpowered, resulting in there being no "choice" required besides whether you want to waste your own time or not. Wolfos, Boomerang Moblin lvl1, and Bomb Fish are all super OP. You dont need anything besides those nearly all the time.
The story is terrible, taking no hints from all the top zelda games. Instead we get the most basic of premises, reused storybeats from link to the past, and zero unique world building.
The only saving grace of this game is the original content that Nintendo has been trying to get rid of: the dungeons. Legend of Zelda Dungeons are still just as fun and exciting and wondrous as they have ever been, especially now that we almost never get to experience them.
