Can you guys add a subtle "ding" or a "whoosh" sound to indicate when the grenade or melee are ready after cool down? I know it's indicated on the screen, but during a boss fight or other battles it's harder to keep an eye on the indicator, a sound accompanying it would be nice. EDIT: Many have also suggested a color change to the grenade and melee tile as well, which I think is also a great idea! Thanks for the support, hopefully they can do this for us come release!
