Hey, that's an impressively long time span! I ditched the Amiga around '92, after my A2000 died of the leaking battery.
It didn't have an HDD anyway, so playing Indy 4 and MI2 would have been a disk swapping nightmare.
Then I bought a used A1200 in 2000 because there still wasn't a great pixel painter on the PC (hooray for DPaint V).
The game I'm looking for was only two years old by the time I bought the A1200 (hint#2). And yes, it's a commercial title and I was pretty stunned, that the "old" machine had an adventure, you couldn't have on the PC

And hint#3 - it's a german/italien co-production, I even found a review from Amiga Magazyn on the interwebs
