A lot more nerve-wracking than what the screenshots might initially suggest!
Making the gameplay perspective top-down is a clever way to avoid having to draw people, but it actually ends up making the game even more stressful since the crowded mass of umbrellas appears very chaotic and (literally) faceless, all while seemingly moving in unison to gang up on the player from behind or make the potential openings tighter (really great swarm behavior by the way). The oncoming newspapers are probably the worst since they appear to run up to the player from out of nowhere, sidestepping any manholes to force the player to move carefully or wait for openings.
Recovering from anxiety attacks isn't too hard once the player understands how to do it, but it doesn't make being stuck in the streets any better since there's always the possibility that a horde of umbrellas will barrel through from either direction, forcibly resetting your progress (or even leading to a game over). The fact everyone else is slightly faster than the player is what forces constant movement to avoid being left behind/overwhelmed.
I could see this game having a couple more chapters worth of gameplay, maybe even an entire city with a "free roam" mode where quests must be met (such as meeting up with friends or picking up groceries), all while battling personal anxiety.
