Outstanding work!
Play the game.
The songs selected work perfectly during the game (I assume the Terminal works to pace the gameplay for a while, and it's enjoyable.) The Jukebox addition is great, to see how it works with the other levels.
I'd really like to see a sequel with custom songs, i know it's hard to develop, but it truly would open a lot of possibilities.
As for the gameplay: Halfway across the game i had to make the expand the screen, i was glad i was able to do that, too. The controls are really sharp, i hardly ever felt it slipped more than i wanted to, Slowing down time worked really well, too. Adding extra lives for those that can't handle these kind of games was really thoughtful, too. I tried to beat it with only one life, and i succeded. :)
The levels are handled really well: Some of the earliee ones aren't a cakewalk as i thought they would be. They are a challenge. Sometimes you get a harder level before reaching an easier one. It surprised me, but it certainly didn't bother me at all. They felt like boss battles.
My only complain is lack of customization of the controls in the 2 player mode.
10/10, 5/5, Faved, and expecting great stuff from you guys. ;)
