This one is really fun, I like the sliding mechanic a lot, and the challenge level is pretty good too! I don't know how many levels you made, but I cleared the first 5, and gave up on the 6th, after hitting around 160 deaths.I did find that the zombies never really posed a problem, they slid in slowly enough that in all my deaths, they were never what got me. All in all, I had a lot of fun, good job!
