''True Calamity'' 100% (Demon) by Subw00fer | Geometry Dash [2.11]
True Calamity is a level that is based off of a Terraria mod that goes by the same name, Calamity. The boss is at the very end of the level, but you can catch glimpses of it throughout various sections, which is something I always like to see in these types of levels. I really liked just about everything that this level has to offer, the colors, the effects, the backgrounds and especially the bossfight.
