But I wish it was more precision based, and the camera was more efficient in level 1.
My biggest, and one of my two gripes comes with level one. Level one really wasn't anything other than "there's a big pile of crap in my way and I have to jump over it." It was to the point that I could just press right and the jump key a lot and I'd make it out A+ Okay. I wish there was some sort of threat, like maybe the camera would move slower and I had to hit certain platforms to keep the music going.
Speaking of that, I didn't really see any connection that the player had with the music(though the music was good.) I wish things you did connected to the music, like getting hit would cause it to cut out a bit.
Really, the music was good, the platforming was good(except for level one), but I didn't find any connection or combination between the two other than that they're both in the same game.
