Very well done but a few bugs
This game had great atmosphere and fantastic music. The puzzles were challenging and in general it was very well put together.
I did fall through the bottom wall in level 17 and got stuck in the black border, though, and had to restart the level. I also had some major issues with the small step platforms - specifically in level 23 -- to the point that I almost didn't finish the game out of frustration.
My character would never seem to "catch" the step even though I was clearly on it. Out of probably 30 times making the big jump to the first step in 23, I probably missed the step 50-60% of the time - though I really feel I was landing in almost the exact location each time. Making those a little more forgiving or at least better fit the graphic would definitely improve gameplay.
