I think it’d be a great idea to add an SFX when enemies drop loot on the floor after being killed; right now the particles of XP and the dropped items blend together making it confusing.
Sometimes I think the glowy particles are from loot so I stand by the enemy corpse for a few seconds just to realize it was just xp. Some other times I kill them and keep moving but then realize there’s the blue flame appearing after the white xp glow so I have to walk back and pick it up.
A subtle SFX specific for enemy drops would be a nice indication to fix this little issue.
