Oh, i think i understand what happened, that's, besides boxes, i think also problematic point of my game, some players after picking up pizza went the same way that was in start, but these boxes are broken especially to provide shortcut to house where you want to go, but i guess, not everyone found it out while playing immediately. About that part of town, felt extremely lazy to work on that, besides of course time, so i just cut that part of map, maybe my problem that i did block it by invisible wall, but didn't left any visible obstacle. Also, my motive to block that part of map to leave only one way to the pizza, so it will feel more like progress when you collect all parts and get access to pizza.
About lighter area of road, that's some problem with baked lightning, i spend around 20 minutes to generate it, and didn't have any spare time to fix it, especially when last baking process was 30 minutes before posting the game, i just left it as it is. There is only one place where you can cross the road, and that where you can see crosswalk sign on road, but because there is only one place where i did that it couldn't be obvious i guess.
About being able to cross the road when you are zombie, it's interesting idea. But first of all, i think blocking the road by invisible wall was not very good idea, cause it's just leaves frustrating feeling, when you see space where you can go, but you simply can't because there is collider. There isn't invisible wall in real life, only maybe that you put inside your head because laws, morals or somethin else.
I really love that you are player that goes left when game says right, because it could be that precious type of players, that explore and find interesting things in locations and don't just skip throughout game with any feelings. If there wasn't any restrictions by time i could make world a lot more saturate and dense, but because it was for me just a decoration to game, i made it really just a decoration without any life inside, and you could really see it even by fact that all windows are lit, there isn't any that are dark, but it's night time, and there's surely some people that already went to sleep, and there shouldn't be any light. So, i guess, in my game it may be the weakest point - going in wrong direction, because there isn't anything where you don't supposed to go. I surely will spend more time on making world less constrained in the future, and i glad i read your comment about that!
About crossing road sign, good thing that i fully forgot about, it's would be very nice to add!
Overall, it's awesome to talk with you about that topic, really apreciate that!
