This was a fun polished game. I really liked seeing the previous performance of myself and other players with the ghost mechanic. That was key driver in getting me to come back.
If i hadn't seen the ghost players moving up the screen, I would not have realized I was missing out on the grapple mechanic. That got me hooked as I tried again and again for those hard to reach chests.
The adaptive audio queues really help you remember to rush when your O2 is getting low!
