It works for me, but dang is this game slow. I made it to level three before I ran out of patience with the slow move speed and gave up. The enemies are okay, it just takes forever to get anywhere and do anything, even after 5 speed ups I feel about what I would have wanted at the beginning of the game. I get that that's probably an intentional part of the theme-- most of the enemies are slugs and snails that are even slower than you-- but I guess I just don't have the patience for this sort of gimmick anymore :(
