Not bad.
The energy of the game is captured well, but I would suggest reducing the amount of flashing lights with vivid colors a bit, and only start increasing with intensity as time runs out.
I would also suggest randomizing each new stage, as opposed to each new run to keep things fresh.
I do think that adjusting collision a bit would improve feel, as there were plenty of situations with one-way tunnels that would separate the civilians, which would make it harder to complete a level.
The controls threw me off for a second, so I would suggest having a temporary display of how to control the game to quickly teach new players.
This could become a much more enjoyable game with these adjustments to start! Good luck.
