Man,you guys are smart!not sure about 7th
but both you posted at the same time so overall smart bros!
I've changed some sprites but I couldnt find the sprite name that matches the half life's wallpuff effect you know when you hit a wall some black squares came out like some sort of spray.I found one in the sprites but thats not it ,I tried changing the sprite it didnt work,wallpuff must exist with another name or something? :/
