DUDE! What an incredible pack! Bought both this and the office pack.
Keep up the good work, I'll be checking for updates :)
P.S: a small request for easying the sprite creation: is it possible that you supply all assets separately (without them touching each other)? They can be in a single file, that's fine, but some assets are attached to others (no pixels between them), so separating them needs to be done manually. Unity, for example, is able to separate assets when they have at least 1 transparent pixel all around them, so 1 click on the png file and you have them all ready to go:
