With a right combination they trigger something, but I don't know what exactly.
3. There was a race section and I reached a point where I cant do the race anymore. Hope that didnt give any %. I wasnt able to win it during the 2-3 times I tried.
I've got all the things done (100%) in Workings section (first part of the game) even though I didn't win it.
4.There is a level called "Ascent" with 2 gems (first part of the game, upper right corner on the map), I only managed to get the lower one and after walking through the level for the past 30 minutes, I got to the conclusion I simply cant do that level for now.
Again from what I remember they were quite easy to get. By the lower one you probably mean the one you have to teleport from the most down right part of this map and the second is on the surface. If you still can't find it I can travel there to check out how I've done it.
Oh, and the game is really fun to play. It reminds me a bit of Swapper - you can solve every puzzle right from the beginning having all the tools at your disposal - but it's much more appealing because the way it is structured let you explore the world more freely, without a feeling of coming from one test chamber to another over and over.
Ok, two more doors to find in Deep Delve and I'll be done.
