The release of geometry dash 2.2 has seen pretty wild additions to the already massively popular game such as the introduction of "lobotomy levels" that test the human soul to its absolute limit complete with insane jumpscares and wacky sound effects like "Fire in the hole!!!" which seems to be omnipresent across every single of these insane experiences. The image of the green face is just the difficulty icon for the "normal" difficulty. There are also a few variations of it, "Water on the hill!" Which uses the "easy" icon, "Rock on the ground!" Which uses the "harder" icon, "Air/Error detected!" Which uses the "Hard" or "Auto" icons, and "Wind from the landscape!" Which uses the "insane" face (There might be other variations, feel free to add them yourself)
Someone please add the actual images of the difficulty icons! (If not, just the normal icon)
