Terra Mania

Race through Terraria as Sonic, with Sonic Mania's movement, rings, sprites and music. Terra Mania is a solo boss-course adventure running inside the original Terraria game.

Creator's note

~ creators note, this game will be difficult, do not stay on normal mode if its too hard, DEFINITELY DO NOT START ON THE HARDER DIFFICULTIES, i did my best to balance the game so it felt right, play nightmare if you want the true sonic experience on how he would play in the real game, I recommend playing a bit of normal mode first though
