The game has everything going for it to be successful, aesthetics are on point, the concept is intriguing (why are we in an arcade to begin with, in what seems to be hell with robots), and the production for the level itself so far seems professional.
My feedback here would be that, on lower end machines like mine there is a level of teleportation back to a previous point when moving in a direction, so perhaps something is off with the movement system?
More options would be very well welcomed as for a menu goes, like being able to pause midway through the game (currently it only lets you go back to the main menu with a y/n option), quality control, motion blur and so (I don't mean to be picky at all, these are ideas that come to mind, yet I don't know how difficult are to be implemented).
As per for the specific story we see about the russian sleep experiment, it gave me a few surprises! It kept me on my toes all throughout, the story was easy to follow, it was well executed for the demo.
That's all, thank you!
