Very very original concept, super intriguing! I love the tourniquet mechanic.
One thing that was a tad awkward was that right after I have to left click out of dialogue/directions, I'm given a QT event where I have to use directionals. It would've felt better to have directionals as WASD so that I don't have to quickly put my hand back on the mouse for the tourniquet inputs.
Honestly would be a quick fix but would go a long way!
