What I find really masterful here is how you created a game, a feeling, and a message, all in a really tiny scope.
I'm torn on the aesthetic. I like how the disjointedness of it all creates a sense of alienation, but I still think it could be improved by having a bit more cohesiveness and a sense of place, like really walking through an environment rather than a billboard. If you wanted to take it further, that is, I understand about running out of time, my game is text, arrows, and squares, lol.
Would've liked to see a timer to compare scores.
