Thank you for the feedback. I originally planned a dash ability but it was something I ran out of time to implement. I had sprint mechanics from the beginning but had to remove it as without stamina it was too easy.
Good point about the lighting. That can be adjusted. I added a light on the pickups to help identify them however I should have placed one on the generator as well in hindsight. I can see how it would be difficult to identify where to go.
