Interesting premise, I was really looking forward to the story, but sadly, I couldn't even get to the next corner - fell of the map, multiple times.
First of all, it has become a common issue now and I don't know why, but the game has no direction whatsoever. Maybe you can put an indication or a map or at least a 2D overlay text of where the character has to go, because I was wondering around the block and couldn't progress.
Second - like I said, I fell of the map. There was an invisible wall on the right side, but I fell off the map before reaching that wall. Then I started walking and turned to the left side of the street, once again fall off the map.
In short, good luck with the game and just because this is a demo, I wouldn't rate the project really, but I would say it definitely gets 1/5 for me, sorry. Fix the game please.
