Echoes of Wisdom may not be epic like Ocarina, Link to the Past, to even BotW, but it's still fun and charming. Challenging? Not really as all the puzzles are quite obvious and even the toughest enemies can be beaten easily with the right Echo. But for those who want more challenge there is Hard Mode. Graphics is akin to Link's Awakening remake with chibi style.
Overall, I feel like it's fun and charming game that has a chill vibe and some action. The wait is going to be long for the next epic Zelda game, perhaps for the new Nintendo console so I hope they keep releasing smaller fun titles like this one to tie us over until then.
