First thoughts: remixed Slender gameplay. It was nice trying to go through the town instead of a forest though there was some strange stone layouts. Didn't like that this was in unity but it does prove beatable once you learn the notes spawn only one at a time. The music was a straight rip from the original Slender game though the pulsing did help give away Herobrine pretty quickly. Main value comes from the fact this game happens in a city environment though do admit the alleyways could be improved upon since they definitely acted more like a escape path rather than a potential funnel yourself into getting caught. Overall playable, and mildly easy if you keep your awareness up about getting away from Herobrine. Also the notes sometimes blend in with the building textures, was running around looking for the 8th note for the longest time until I finally decided to hug any surface that a note could be on. Also I do enjoy that just because you collected the notes, doesn't mean it's over. You have to make it back to your car. Hopefully the player remembers where they started. Also the tanker truck on the little car was a bit bizarre to look at. Guessing this city was supposed to be a ghost town?
OH and one more thing, though this would up the difficulty by quite a bit, if you plan to remake this, add more indoor areas, found myself yearning for more places other than just the one.
