Shoot an arrow into some hanging headless guy

Arrows can support your weight

Plant an arrow into a platform

Push the first hanging cell all the way

Miss a jump and fall into the spikes

Light an end level torch

Push the first crate you encounter towards a pointy place

In Level 3, avoid the bats

Defeat your first archer skeleton with the help of the crate above it

Say No when the game proposes you to Continue

Miserably fail and reach Game Over
