The game is interesting, but very, very unclear, especially when it comes to medals, that's jus my opinion. My thoughts:
1. In "how to play" there is a suggestion that if I will play fast enough I will get more time. Either I am still too slow or it doesn't work because I didn't notice any time bonuses or something.
2. What is the relation between the scores in the game and the points on Newgrounds highscore list? By the way, there is no spoon I mean the list for Fast 50 or Dash, or maybe it is the list in the game but if it is then how do I know if these are my best scores or is it a summary list? If the latter, then which score is mine? There is no highlight of the latest score.
3. Analysing for example the 500 Runner medal, what does it mean that I have to score 500 in infinite? How players should understand that?
4. The number one medals: again - not understandable, number one on a highscore list?
The game definitely needs some upgrades and more explanation, but I can say it is an interesting thing to play.
