Terrible
The kind of puzzle game where frustration is caused not by the puzzles being difficult, but by the fact that the only way to solve anything is to run your mouse all over the screen, hoping you'll run across something that is useful. Even after you have everything, though, it's still a challenge, because you have to combine objects that make absolutely no sense (e.g., instead of a hammer and chisel to quarry rock, you need to find an emerald, an emerald holder, a mirror, and a tripod to build a laser). Even the hints are worthless: the game will mark rooms as complete that aren't, or suggest that you click on a highlighted area that you can't interact with yet.
Terrible, horrible, stupid, annoying. Only finished the demo because it is hot outside. Skip.
