Note for other people that would try the game out, the TypeError mentioned by previous testers should be fixed, as well as the interact key mention being added.
Really cool ! The mechanic is intuitive and quite nice. I really like the doom reference in the thumbnail. The thing I'd add, is the ability to keep firing while holding the fire button.
Really cool concept. I think it might benefit from some sound, maybe a little music but mostly some feedback when petrifying someone. Be it audio or/and visual It overall might make it more readable, especially for people like me that never read the instructions.
