I was stuck for a very long time, and for this not to happen to you I
tell you. You win the level after the falling one and the one were the
mummies face you and you are on one with the puzzle. Go in the room and
you will see a short movie and a door opening. Go in it and take out the
torch. You will find a bridge will blue stuff (NOTE: Only visible with
torch) then croos it and light the braziers. When you are about to cross
it a movie appears and the bridge turns around and red ones appear. Only
step on blue ones by jumping and when you get near the other side a
cut-scene appears. 2 reds in front of you. Go bag and step on the blue
one, then 2 more and it becomes normal. DON'T touch the red ones and
cross. Then another doors opens. Go into the room (With the torch) and a
bridge appears. Cross with the torch and light the braziers. Then the
tiles move. jump and jump until you reach the other side (took me a few
tries) then solve the puzzle and you will get a boomerang. Kill the
mummies and you win.
