About Mortimer Beckett and the Time Paradox Game

it took me several attempts, but i managed to complete the game in 57 2... i think it could be done in less than 55 minutes, but that'll take much effort and even more luck (i.e. placement of items)... and yes, i do have a life!

Time portal in Egypt, give the man in Luxor some fish, he will move out of the way; you will see glyphs on the wall behind the time portal. You need the glyphs to finish the columns to get the matches for the light house.
To get on space shuttle, help the scientist get the robots unjumbled at the factory and install their brains. He will be grateful, give you an item (forget which one exactly) and allow you access to the shuttle that will need the record in the jukebox on the left, and the emittor on a small opening below the iris-door that will open the portal.
The puzzle door on Excalibur is actually pretty easy. On the top, sides, and bottom of the puzzle are these little arrows that you can move the colored stones. Directly underneath the top row of arrows are colored stones that tell you which color stones you need under. On the right, there is a guide that lets you know that you need biggest on the top and go down the smallest on the bottom. It takes a few minutes to move the stones, but it will work out. If you just focus on one color at a time, once completed, it will disappear leaving you with just the other colors; process of elimination
In the French Revolution. The puzzle in the cabinet is solved starting out in front of the prison. There is a tablet with writing on it backwards; use the CD to read the text properly. It has a story that relates to the figures in the cabinet. About a little GIRL going to a LIGHTHOUSE playing with her CAT by a STONE STATUE going out to eat a PRETZEL and listening to a CANARY...not the exact story word for word, but I think you got the hint.
For the stone puzzle on Blue Island, it's a pretty long sequence. First, you need the hammer. Go under water in the zone that has that stuck up little man with the stick in front of the ship loaded with cannons. Second, go under water and use the hammer to bang on the chains on the left side of your screen. The loud noise will wake the Leviathan. Third, you will ask that Leviathan remove the curse on the captail so he can give you the missing map fragment. In return, he wants the spyglass. Give Leviathan the spyglass, he will lift the curse, the captaim will give you the map piece. Take the map piece back to the governor and he will give you the rest of the little stone idol. Use the stone idol on the rock puzzle on Blue Island. The oject of the puzzle is to use the little U shaped groves by rotating them and moving the ball to the opening in the bottom. You can only move the grooves a quarter turn at a time. Once you meet up to pieces to move the ball, go to the U piece the ball came from and give it a quick rotation to avoid the ball going back. It is tedious with the backtracking, but that is what you have to do.
For the code in the Crystal tower, it is 01001010; it is on the fourth or fifth line of code you get from the guy downtown when you give him the laser ball ticket.
The airconditioner in the Wild West? In the zone that has the sheriff with the safe (foget the exact name). The building next to Wong's imports has a set of flexible metal tubing standing up.
