Haha see I said I had problems with difficulty! Yea the heat crank definitely could use an indicator or something. I had a friend record some voice lines that I had planned to pop in to explain things more clearly AND to help give you a heads up on what the enemy was doing but time got the better of me there sadly.
For the heat crank, after you plug a cell in you have to click and hold to grab the "top" of the stock. Then rotate your mouse in a circle around the middle pivot point.
Thanks for giving my game a try!
