So I think the concept of the game was good, but I think it lacked execution. I was pretty lost in what to actually do in the game. But when I looked at the description it all seemed very well thought off and I gave it another go. I personally couldn't trigger regardless of how long i held down 'E', this may just be a glitch or bug.
I did however, quite like the music and the main menu. I think this has the potential to be really good if the events were made more clear, and things like the jump and controls and lighting is tightened up.
Well done.
