There's not much to do besides moving around and trying to crawl your way towards power-ups. I felt that the path to getting certain power ups was not worth the effort, especially some of the ones that give you time as you'd use it all up trying to go back from where you came from. I did enjoy the slight horror aspect and the music did its job well to creep me out a bit. Also, I'm not sure how I'm supposed to add my score to the leaderboard.
