Meet: Грішникович (Hrishnychkovych).
What can he do? I don't know. But I know that he is not your friend if you meet him by chance.

You can only find out by meeting him, and even then it is probably not enough.

Collect all the boxes on the level, but watch out for Грішникович - he accelerates over time, and if you have a lot of boxes but he is faster than you, then time is up. Hurry up to collect the boxes - there are more and more of them. You will meet the reason.
