For Derek Deagle, it was another day on the job.
Classic.
I liked this entry a lot: The narration, the atmosphere, the music, and the visuals.
It took me several tries to make it to the mirror realm because I kept dying and couldn’t find only one healing item, though, by the time I was done, I had 3 to spare.
Movement felt strange; the mansion didn’t seem to fit your chosen grid size, and I found a spot on the first floor that, if I walked to, would take me through a wall out of the grid.
I was able to cheese the combat a little. I could attack through walls. I discovered this when I inadvertently killed one of the spiders guarding the crystal ball while in the bathroom with the medkit. My knife also seemed to hit two spaces away in the mirror world.
These are minor quibbles, however. I enjoyed my time with it; it was a fun and tense experience.
Great job!
