My second run went waaaaayy better than my first one because I read the instructions. Funny how that works! I really liked the puzzles but the first one with the levels I just don't know how I solved it. I solved it a couple times and different doors opened and I don't really know why.
When I fell into the lava I respawned under the ground.
The mood was wonderful and I liked the visual effects but I would have liked more torches. I placed one or two and then I just played the whole game in darkness. I haven't finished it yet so there may be more behind a door somewhere but I'm having trouble proceeding past a really dark large room with a bad guy in it.
Overall a good effort with great atmosphere.
