Fair, although, as with the other game, this was originally intended as a standalone game and html5 doesn't handle mouse input well as it stops at the border of the browser. A controller will alter the experience.
The gameplay and slow turns, yes you are very correct, it is slow and it does amount to quick and unfair deaths, but there is a sense of nostalgia to it. I used to play games like Alone in the Dark and the first Resident Evil games and the tank controls in them were very frustrating.
I guess there was a bit of a quest for lost time, a fragment of the past that I tried to convey. The visual look of Silent Hill, the controls of Resident Evil, the stupid scares and unfair deaths of Alone in the Dark. I hope I brought a bit of context to my choices in this. :)
