luv the game bro i loved the sneaky way you had to get the quartz to the magma using sand gravity stuff i was just asking about if theres a level below magma and what helmets do
Thanks! Glad you enjoyed Nix unlocking. As for what's below magma, there is technically a little something down there, but I won't spoil too much for other players here.
Headgear is purely cosmetic and doesn't affect gameplay. It's more of a late-game collectible, and each turtle has their own unique headgear to unlock.
