Selfishness

The mid section drains your health more than you'd think, and since potions aren't plentiful, it's hard to enter the late section with full health. Unlike some short-cuts where you can easily pass by dragging, this layout doesn't even let you drag, so there's no solution other than raw accuracy. It looks peaceful, but it eats up way more stamina than it seems and is quite tricky to handle...

The final spike is tough, but it's not long... I think the most important and difficult part is playing the runs and drills in the front well to enter the final spike with full HP.
