Yes tokens are a great idea! Actually thanks I would probably create ones dedicated to the HYPERFAST sub-system!
So they have 20 actions total per PC (which is really less). The system is made to be playable in a 1h30-2h max session. The idea of a counter is also to be customized by the Warden to have a slower game or something crazy with like only 10 moves (“BOOST MODE ACTIVATED”).
Would you be interested to have a blog post about the HYPERFAST system?
