Although with time it seems to have developed some non-detrimental UI bugs, it is still one of the most fun pastimes to casually come back to. It is both straight away easy to get into and challenging to get far, and if you want to it can even be quite relaxing. The progession system and daily leaderboards make this game a hard one to "put down" once you've started playing. And different courses with each day make it enticing to come back to. An added bonus is the active community of level designers who display some stunning mastery of the in-game level editor.

Most definitely worth the price.
