The largest walls at the fastest speed seems outside my ability to dodge but otherwise it's a pretty good game.

This is really fun and rewarding! If I had one suggestion, it would be to add statistics or text to the death screen, but it's great as is.

Great game!

@Hackerz, sounds easy to add, what stats do you have in mind ?
High score ?
Number of played games ?
average score ?
A time/score scatter plot ?
