Supertux 2 0 3.3 with Forest World
In Kneep-deep in the depth solution
get on the tree limb use the keyboard up arrow
to jump high enough to make it to the other side
(run and jump check-box must be set in options)

go down collect fire-flower skip the bottom jump for now,
jump back up eliminating enemies skip the bouncy at the top
run into it you must get to small size to make the jumps at
the bottom, complete the jumps to the switch
once the switch is stepped on the lava quickly rises,
run and jump back up stop when you get on the edge
of the wooden block stay there it will rise above the lava.
when you are at the top (the wood stops) complete the jump
over to the platform and run to the key.

Note you wont be able to avoid the rising lava if you have
to dodge enemies at the same time.
