Updated game file

I had some reports of crashes on the original downloadable file for the game. I have found at least one issue with the project and I believe it's all fixed now, but if any bugs are found I would appreciate hearing about it in as much detail as possible! In addition to these fixes, I have made the controls a bit more clear in the beginning after observing a playthrough of the game. Finally, I have added more shadows/changed the lighting in each room to better build atmosphere. If anyone has any suggestions, please let me know and I'll work that out!
