I'm thinking of making the players move just a little bit faster, but it starts to feel strange when I increase it by more than about 20%, so it won't be much faster. (Don't worry about making me feel forced :), that message at the start was mainly for people who went too far.)
Are you playing on keyboard or controller btw? I noticed that the double tap is a bit annoying sometimes on a controller so I might add a run button, although that would make the game slightly less simple...
