Addictive; fully clocked the game in a short time. Definitely recommend playing it.
You needn’t use the badges — they have no penalty but they’re mainly aimed at a more relaxed play style and children. There’s no other use for the jewels either, hence ending up with the 500k balance of them.
Sometimes frustrating as the ‘Ground Pound’ move is mapped simply to ‘Down’ which is also the move to create a yarn ball. This caused me to pound off below the screen which infuriated me on the more challenging maps. Also, the sound of Yoshi when you ‘Flutter Jump’ is quite irritating but you can normally shut it out, the other sounds and music are lovely.
