I was beginning to think that people were totally put off by the size of the level ("Oh no, I'm not even going to start this #%$%") and oh yes, the trampolines.
Well, good news in 2 ways: the level is actually not that big, concerning the amount of puzzles. I see a trend in this community to create levels that are as compact as they can possibly be. While I admire many of the puzzles (love your beaches, Liz), this turns out not to be my way. I'm enjoying my little story (such as it is) and am trying to incorporate puzzles into a natural environment. Hence the design. So don't be put off, you frantic gamers out there!
Secondly, the trampothingies in this level are mostly used with the objects, not you. So you can keep your lunch on the inside...
Now then: the bridge-like structure in the upper left hand corner you can totally ignore, as nothing will happen. It could be there just for show, but Dutch scientists are still investigating...
The first, and most difficult area is the Tomb of Queen Pecunia. I'm excruciatingly proud of this one, as it's actually 2 puzzles rolled into one and completely intertwined. You need to make use of the ice & trampos in a N-S direction to open the tomb. Read the 1886 diary for a hint on the 2nd puzzle...
You could experiment here until you're blue in the face, but it's not the season for that now, unless you live in Australia or New Zealand.
So: OBSERVE. What needs to be done to open the gates. How do I get something, anything, on that spot. And: which objects go where?
Note there's a plasma cube stuck in the light blue gate, so a little extra is needed there...
First, find ways to move around there without disturbing anything. Most important! I had loads of fun discovering ways I hadn't planned, but they fit like hand-in-glove. The most obvious is the light blue teleporter, of course. But try walking up into the dark blue one and then press right. * Works the other way too. The third ice lane from the top will come in very handy, and then there's the regular lane just below all the destructible floors. From left to right just a simple boink-boink and boink-boink. There's more ways, but it's up to you...
The red boulder is a simple hint for the tomb puzzle, so just put it in the water. Then look at the dark blue button, as that should not be too difficult either. After that......to be continued..... ( maybe.....

)
Oh, and Liz, about those signs: there's more, so don't give up!
* I was wondering why quite a lot of people seem to be discouraged by trampolines. Is it possible that not everyone realises that after the first trampo you can change direction (well, you knew thát) by simply holding down the desired button until you've passed the trampo, and then holding down another desired button? If you didn't, you do now, so no excuses!
