Not bad, the easing and running is really good. Puuro brings up a point though, I don't exactly see where it's going yet, but looking forward too what comes next.
Also, one more thing. At first when only the green guy is running there's no dash lines on the ground, but when the other purplish guy appears and they start running the dash lines appear from under the green guys foot.
[Do you get what I'm saying, it's kind of a long sentance?]
Over all, nice job.
