I guess it's jus how it is. but i like how its short because it makes it much easier to complete unlike shrikti temple (cant spell) i soloed the tree of life many times. i find it to be a great ending dungeon in mooshu also there's 2 secret bosses in there but i forget where exactly one of them is located. the other one is located in the dojo past oakheart (with the webwalkers crawling around) if you want to fight the other one just keep trying to enter every dojo with the lights off.
