Always loved these games!
there is a panel in the Japanese room door,
you can move the large picture in the dinosaur room,
and there is a removable panel under the tepee in the desert room.
For all those who said correct code for chest (SPOILER BELOW, DO NOT READ IF U DON'T WANT TO KNOW)
The code is found in a panel behind the Japanese style wooden wall.
If you think the other one is wrong, make sure the order of all codes to go from the vales of
1000 to 100 to 10 to 1. Worked fine for me. Great game by the way, 5 stars.
Great escape, though too easy.
This was cool. The difficulty is a bit high for a few puzzles, but I stuck with it, gave it a minute, and worked everything out. The only critique I can think of is a couple items don't have hints, you kind of have to click randomly to find them. But it was worth it to find that last key.
So far it's a good game, but I got to the dinosaur room, got all three gems, and have no idea where to put them.
