While in the air or on the ground, you wont be able to wall jump after you do a light melee. I do understand the need for the heavy melee, but the check for the light melee should be removed as it does not keep you in the air for any longer.
while on the ground, if you melee at all, for the next 2 seconds you wont be able to wall jump, i understand why this is needed in the air with new wall jumps, but on the ground, this should be fixed, it makes the wall jump feel inconsistent.
