There is some negative feedback about the mouse sensitivity, and controllability and it was truly not without reason. I wanted to fix it, and I think it succeeded in some level, if not don’t hesitate to tell me. I also added an ingame menu where you can change difficulty level, so if unconfortable for you holding keys for about 3 mintutes down it can help you. There were a huge bug  just before the end, and it freezed you, it is also fixed.  If you tired and frustated by the controllability give it a second chance, if you not, you can try it now, here. And a screenshot of the menu:
