I ran into a glitch where I was holding two artifacts at the same time and I couldn't put down the yellow one. I original put the yellow one into the holder right below the pedestal (where you can place all three artifacts) to open the door and then grab the red one and went down. After dying, I respawned with both. Luckily, exiting to the menu and coming back fixed it. By the way, does the yellow one have any special powers?
I'm not able to play the game. No matter what browser I try, it always says I need to download the latest Adobe Flash Player. It still doesn't work after I do that (it even says it for Google Chrome and it updates for it automatically).
I've played the game in the past and really liked it and I'd like to play it again.
