Man, I love this game. I can't even tell you how many hours I put into it...because I put in so many lol. But I finally got all the medals and I've mastered the game. In fact, on my last run I was running for 40 mins straight before I finally got bored and committed suicide.
I love how simple it is, and how there's only one button to press. The concept is fun and great. I'm never going to get the main song out of my head for eternity, that might be the only downside. Also, for medals like "swing 30 times in one run" or "float over fans for 15 seconds in one run" they should be worth more. Not necessarily because it's difficult to do those 2 things, but by the time 30 swings spawn for example you'd have to be running for like 10 minutes.
Hope you make more games like this.
