Another hint: Its a 'first person' point and click adventure game for PC, Amiga and Atari ST.

aaaand here's another screen :)

Something with vampires probably

Here's an actual in-game screenshot, (this is from the AMIGA version, which was vastly superior in the sound department, like almost anything on Amiga at the time.)

I don't know what game that is. But I want to play it!

Yeah its pretty rad and not so well known, some of the puzzles can be really far out though, and you are basically limited to only 1 to 3 screens until you can make progress so it can get a bit boring if your stuck.

Hopefully that counted a bit as hints ;)

The Prophecy AKA: Ween: The Prophecy

correct! your turn!

Next

Pepper's Adventure in Time

Hmm, now I wish there was a game called "Sgt. Pepper's Adventure in Time".

Thinking about it, a Beatles point & click adventure would be cool. Or a Jump 'n' Run ore something.

It couldn't be any worse than the movie. :P
Anyway, contact the Michael Jackson estate; it owns the rights to all of that stuff.

Sorry, Its not going to be quite that easy ;)

Dirty tricks :p

Looks like you need another screenshot (only slightly cropped)

Spellcasting 101!
