First off, Delta X is such a cool name. Second, you got something sick here, I really want more! I love the speed mechanic, I got it down on my second run and had a really good time trying to see how fast I could make it to the end, and wondering what shortcuts I could take to get there faster. The visuals are just enough, and I'm a big fan of the little smiley near the end :] But yeah, my only issue is that I wanted more! I was figuring that had been level one, only to go "That's it?!" when I saw there was just the one! It would be a big task, but if you could turn this into some sorta endless runner style game with the same speed/explosion mechanic, you'd have something super special. Good stuff!
