Was going to do that but I couldn’t finish it in the time I had. The use for that item was just to not feel excited, I guess. That item also has a faulty vision. Adrenaline is the most useful one. There is also a special item in the unfinished game mode and it’s a syringe that recovers your health.
Also yes, luck, vision, adrenaline etc are items
To answer the other question, if you win, the entity dies. Was gonna put some lore drop
They also said that I can fix the always-losing issue in the extra game mode so i’ll let you know when I fix it!
