Hi DonutSauce,
Thank you for the feedback, we have actually tweaked the movement a little - whilst the distance you can move per "jump" has not increased, the recharge of your stamina is now 1.5x faster.
In addition there's a new soda machine perk called "Stamina". When you buy and drink this soda it further multiplies the distance and recharge by 1.5x (helps as the zombies now get faster with each round)
Expect a new release this weekend!
James
