Loved it
If you ever played DM or Eye of the Beholder... give yourself a treat and get it.
Ironically, as oldschool as it is, I found that the game and especially the truly oldschool movement system... which originally was invented due to hardware limitations,... didn't feel outdated at all, but rather refreshingly different from this decades "mainstream games". "Step by Step" movement also worked incredibly well as a basis for all the quite well made puzzles in the game.
It's got a certain "no nonsense" feel to it that really lets you concentrate on what the puzzles are about, as it doesn't distract you with the particularities of precision positioning that would be required with any free/FPS style movement system.
So, yeah, back to the roots I say!
