Unfortunately, as a Yoshi fan, Yoshi's Island at SNES, I have to say I was terribly disappointed. However, this does not mean that the game is bad in itself, only if I compare it to other Yoshi games.
I am someone who has always loved the music in Nintendo games, especially in Yoshi's Island and Woolly World. Unfortunately, the music in this game is terribly bad: it is more or less the same song / melody in each track.
But it is obviously not just the music that disappointed me. Even the animations at Yoshi, the eggs, etc., are considerably worse from Woolly World. The switch is also not strong enough for the Unreal Engine 4 and this means that resolution is very low, especially when playing in Handheld.
There are things that are good too! I like that the tracks have two sides and that one gets the task of finding things in the background. This gives the tracks more replay-value.
