I’ve been having trouble finding this movie for a while now.
It’s animated movie. I only remember a small portion of it.
The hero is kind of in a dungeon with a sword and two keys. He climbs up the mountain like surface and there is heat. At the top, a door/gate of fire exists, the hero throws the key and the gate opens. Next, again the hero walks up the surface and this time it’s smelly. When he reaches the top, a gate made of green liquid exists. He throws another key into it and the gate opens. Now, the hero reaches the third gate which is made of swords or knives which are constantly moving, more like attacking. The hero doesn’t have the third key, he uses his sword to fight the gate but his sword breaks.
That is all I remember. I watched it somewhere between 2005 and 2010.
Thanks in advance!
