Welcome to the RnD World Challange!
If you don't want to discover by yourself anymore you should read this WALKTHROUGH with all the hints and tricks.
Let's start.

1. THE BEAMER

If you start the level you must collect the blue element in front of you. You are able to drop it. If you do, you'll see that it's a carriable beamer which lasts forever in the whole game.
After you dropped you'll be located in the CENTRAL TELEPORTATION STATION (I'll call it CTS). Read the two envelopes carefully before you continue. Take the blue teleporter firstly.

2. PARTERRE

Now you are in the parterre, the cross point of many attractions.
Go through the south-west tube to get to the "CENTER". The big room which leads to the most important places: The dungeon (south), the National Coin Bank (Okay, that's perhaps not so important), the world's clock (with special measure, don't try to understand) and the elevator "RockFaith 1.0" (only some CE-fun). Collect the white key (east) and take the carriable beamer (CB). Ah, before I forget: You'll notice that the CB only works if you stand on empty space, no dirt. Take the red Teleporter this time to go to the Diamond Factory. It's also only some CE-fun, I said, I did not want to put it to the i-net firstly. No matter. Go through the white door (which has to be unlocked everytime with a new white key which appears again when going through white door). You have two different transportation belt switches now, a green and a red one. The red one stops the random output of rocks and diamonds, the proportion of rocks and diamonds is (averagely) 1 out of 10 (1 diamond out of 10 rocks of course).
The green belt is more important I think, because it drains the diamond storage if it's filled up to the cutters (blue things which destroy the rocks). You can actually set the diamond factory off, that doesn't matter.
Take the CB again and now the green teleporter.

3. UPPER DUNGEON

You're in a small room with a tube exit and two yin-yang signs. Here's a hint: Switch the yin-yang and you'll teleport into a room with a cross in the center. The cross doesn't matter so much, the light switch is more important. The invisible walls lit you'll see a small corridor hidden in the darkness. (Be careful with the gems you collect here, 12 could be your death). Take the CB and the green telep. again to get back to that room with yin-yangs. Now go through north tube and anlong the way you've just seen with the light switch.
If you reach the end of the corridor you are teleported automatically.
Now you are in a room with magic balls in center. Do not use the switch or you'll discover a deathly secret. Go to NW corner and you are teleported autoatically again. This is again one of the little hints. There's the YELLOW KEY. Pick it up and then use the CB and return to the magic ball room. Now co trough east wall (walkable, :-)) and along that short corridor to the room with the port. Go through and be in a big circle of rocks. You're now in a new section.

4. EAST AREA

You're now in the furthest east of the level. Firtly go south and then east to see that green pipe. If you switch the blue box a purple emerald will fall outta it. The belt is the same as the belt for Diamond Factory. If you did not set it off it'll bring the emerald to a gap: Either it falls into the pig room or it gets to the penguins (both is just for nothing :-)). But you won't get far because there are a lot of doors which block your way. You have to find all of the colourful keys around that level.
So take your CB and blue teleporter towards PARTERRE.
Go to the CENTER and through south time gates into the upper dungeon.

5. KEY RUSH

Push the red block aside (don't get irritated by the time it needs to push the block, it's set to last that long) and go through south tube. Be careful with the amoeba drops and the bug when you get the RED KEY. Take the CB again, here's nothing interesting anymore and then the green teleporter.

Now you've got a RED KEY and a YELLOW KEY, but two ones are missing. For that you'll have to get to the CENTRAL FLOOR, an area you've not been in yet. Got to the room with the magic balls and head east again to get to the port which gets you to the rocks' circle. If you're there, go NORTH into the seemingly empty room. But there is a giant hint again: Two of the walls of the bigger circle around the rocks are walkable. Go to the gap between wall and rocks and touch the rock in the middle. It's a teleporter. It gets you to a room witch is connected to two other rooms. You'll notice that you can move straight only, you can't stop half the way. So you must not get into a trouble spot. Go through the SE tubes and get the GREEN KEY below. Head back upwards IMMEDIATELY or you get into a trap you can't exit anymore, remember, the CB works on empty space only! Head nort, then east and get the BLUE KEY and escape with the piece of emty space that just appeared.

6. MORE BLOCKADES

If you headed back to the room with all the doors you have now the keys for you'd see that the way is blocked by a transportation belt witch rocks on it so you cannot go there. So use the green teleporter to the magic ball room and go to the walkable walls again. This time DO NOT go through the port but stay outside the walls and snap a hidden invisible NORMAL WALL which is a little in front of the visible wall.
Now you are in the CENTRAL AREA again. Do NOT move firstly, stay where you are. If you moved a growing wall would block the way down. Your speed was set to ULTRAFAST automatically when you beamed. Try to go to the BLUE TRANSPORTATION BELT SWITCH as fast as you can to let the rocks block the way of the growing wall. If you did so the way is open. Go through the timegate and see the light switch in front of you. Light it and notice the corridor like this in UPPER DUNGEON. The steel wall behind the switch is walkable so that you can go through straightly. Follow the way and get to the ORANGE TRANSPORTATION BELT SWITCH. Set the belt moving towards the direction the arrows show and use your CB to escape.
Before you go to the Circle again, use the blue teleporter towards the PARTERRE and set the SWITCHGATE SWITCH to open a last nasty door blocking your way.
Now head to the circle.

7. THE DISCOVERY

If I was you I'd turn the player speed to maximum. For that go WEST out of the circle and switch the "+" a few times tu set speed. Now head back towards the now open doors and go through. Quite below there is a chain of many BLACK ORB BOMBS. go to the center, pick up all the coins and use the TERMINAL to make the bombs explode.
The bombs' explosion's reaction is a hailing of gems. To stop it, press the now available balloon switch. Collect as many gems as you want.

8. A LAST HINT

Use the CB to go to the PARTERRE MAIN FLOOR and then go through NE tube in order to enter the right room with the green door. Try and got to the other side: You'ss be able to. Now you'll know that there's a hint again. Go the time gates towards the upper dungeon and walk through the red door whose red key you have collected yet a long time ago. Go south into the room with the two of the spaceships. Push the bomb into the acid and there's the GREEN KEY next to the acid basin. Use the CB to return to the room in that you know use the key to walk through the door. You are now in the LOWER DUNGEON. Go along the corridor, be careful with the yam-yams and switch the lamp to open the exit. Use the CB and go into the upper dungeon room with the two spaceships. the red wall below the tube isn't there anymore now. go through the corridor and enter the way you took to get to the ORANGE TRANSPORTATION BELT SWITCH. You are able to walk through the seemingly indestructible wall below the switch. Follow the way until you reach the FINAL EXIT. There's your time you needed.

You do not have to exit now, you also can discover anymore, looking for more walkable steel walls (that exist!!!) and discover on.

For any questions write to me at the forum.

Yours
