I was delighted by this game. It's in the author nilsf's custom javascript parser system (I believe), which has always been on par with the big 3 of Inform, TADS and Dialog.
It's a short two-room game. At first, I was entirely stymied on what to do. There were several cryptic messages and a way to die but that's all. I was about to post a hint request, but carefully replaying the game to describe the setup gave me the hint I needed to succeed.
The second room had a lot going on. I felt like there just wasn't enough info to proceed, but when I finally figured out what the vials were for, I was really impressed with the solution. Finally, figuring out the skulls was a real unusual thing that was not something I've seen very often at all in parser games.
So, this was great. There were a few typos (I think a wall was called 'souther') and I had trouble referring to one vial, but otherwise this worked great, and I'm impressed it was put together in such short time.
