yeah, it is not super clear at the moment. I want to add some partials that move towards the timer when you collect.
Collecting an arrow extends your time by 0.5 seconds. Currently, the time until the suspect drops increases by 1 second per level. So early on, it is not critical you collect many. But as you get into the later levels, you need to collect almost every arrow to succeed. If I continue to work at it I will try to make this more clear and work on the progression.
