Although short and succinct, there is palpable terror and fear throughout the runtime, with the creature continuing to pursue you that made me hold my breath in the subway. The audio cue that accompanies the creature when it's behind you has you paralysed with fear throughout. Accompanied with the frustrating element of people getting in the way, this really had me almost yelling at the screen in order to scavenge the right amount of money to escape.
Although the story elements are pretty threadbare, this definitely had me wanting to know more. The Pulp Fiction-esque mystery element with the briefcase, why this creature is continually dogging you, I'm invested in finding out more and where this story goes.
Hopefully the full game won't be the same mechanic throughout - I think you've got a really interesting concept and with the collection of money there could be scope for upgrades/ways to fight the creature etc. Looking forward to discovering more from you.
