Thanks again for the feedback!

I took a look at it today, and it does look like, as Tess said, we introduced a bug in the melee system right before we released the game. The result of the bug is that players don't have a limit on their rate of melee attacks, while enemies have a delay in decision making before they attempt to make a melee attack - so players can attack far too rapidly while running through a pack of enemies, and enemies attack far too slowly, so they don't hit the player often when they're pushing past.

For the tutorial, do you think it would make the wording more clear if we removed the O button from the tip and just told the player to use the right stick to fire? Or is it the right stick icon that's confusing?
