great game
good game and for people struggling on the endless tunnel here aresome tips: the elevator (the one in the sewer area ) can lead you to the place of colour.
once there its simple to atain colour through arrows.
then the moon is the key to releasing that colour.
then you can get through the endless tunnel.
its pretty criptic but not actually that hard
anyway great game if you still cant beat it then heres some SPOLIERS!!! that will
