Test Chamber – Super Mario Run's Hardest Bonus Level

Super Mario Run only has 24 levels, but if you find each level's 15 bonus coins, you can up the number of levels from 24 to 27.

Of those three additional levels, the final bonus level is easily the most difficult. It's filled to the brim with buzz saws, only has two mushrooms, and no enemies, surprisingly. You can check out a playthrough of the level below.
