A1: Stand on one segment at a time in the centre of the room then go into the room that corresponds with the segment......pull the left and right lever but as you do back flip or you fall in a pit and have to find your way out....wen you pull both levers a centeral door will open go in there and there will be a challenge..defeat all four challenges

A2: There are 4 switches in the middle of the hall of seasons 'fire, earth, air and water' when you stand on one of the switches three other doors will open (three different doors open for each different switch) , through each door is a lever to pull, 1 of the three levers is the correct lever you should pull to enter another room which you have to puzzle out to reach one out of four crystals. but if the correct lever is not pulled the trap door opens and you fall down into the "basement of doom" which is a nightmare to get back so I advise you to save it before you pull any levers! but you will have to be down in the basement after youve got the crystals. Its best to search on google for a walkthough on the hall of seasons level on which doors to go though and which levers to pull. when you have all four crystals you then return the the basement of doom ( try and enter the air symbol way as I found it easier) when youve dropped down into the basement find the " furnace room" ( turn right if dropped through the "air" trapdoor). complete the furnace room which you basically make your way up and round to find valves to turn then exit the room without getting killed by the trap that is set off when all valves are turned. then make your way back round the basement of doom (advise to go right, but either way is the same length to go!) until you find the elevator which takes you back to the hall of seasons, you will see four platforms in the middle of the room moving up and down, make your way up them carefully.
