Hi Laurette, I meant to move your post about the darkness of the game over to Glitches, but not the entire thread - sorry about that. One of the mods here can move the rest of the thread back to Adventure Game Discussions if they wish.
But to answer your question, yes, the game is very dark, and what I did was to increase the gamma/brightness settings so that I was able to see things properly. There's no way to do this inside the game, as I recall - you need to do it outside the game. For my graphics card, I had to go to the NVIDIA control panel, which is where the gamma/brightness setting is found.
