Ha! Yeah, one of our team members is named "12" - there were only three of us. You're right that more enemies spawn on higher tiers, but it does cap out at a certain point. My high score is 55,000 points. I've found that taking your time, and not rushing too fast, while prioritizing food pickups is a good way to go. The hands don't increase their chase speed, so you as long as you keep a healthy distance from them, you can plan your next moves! Appreciate your feedback, and your playthru!
