Besides that people seem to claim that the game evolves into something else that deviates from the presented gameplay.
But I have to disagree on the games initial presentation, because clearly the game seems to be a "retro" c64 / atati game that would have canonically been released when the restaurant was open, but this notion is thrown away because it doesn't really feel that retro. The font looks to be a low resolution version of that regular font that's shipped with every PC today, and the graphics look to be a blurry mess (And this is an easy fix, mind you).
But hey, It's free so I can't argue about that.
