We've just pushed an update containing these changes:
Further balance of the number of traps: sawblades, projectile launchers, acid drops, floor mines, laser beams, etc.
Removal of the "H" (Hero Stats) keyboard shortcut, which caused issues in online cooperation mode. The Hero Stats is fully accessible from the pause menu.
Fix for the visual error of ammo indicator sometimes being stuck on the screen in front of the player, when playing with a controller.
