Extendable ropes which you can also swing back and forth with to achieve longer momentum-based jumps (these all seem to be preplaced)

Can only die from falling more than two screens down
Four different weapons but the projectile behaves the same except for the torch which fires bouncing fire bullets
Birds can pick you up and drop you off elsewhere (randomly? Only useful to get out of a couple of dead end pits)
