This is one of the most underrated games I've ever played! I think the main reason I like it so much is because of how free spirited it is. I got enough stuff for a Bonus and I only got 58% of the items. I think that's amazing! It helps that you're this cute penguin. Not even having a 0 point medal could I be turned off from this!
There's so much going on in every level. You can really do it at your own pace. The sounds are so whimsical and everything is so beautiful. I was happy the whole time I played this. The enemies are quite unique too. There was so much to explore!
