This was a wonderful experience! The main mechanic was easy to get into, loved the inclusion of people in wheelchairs, and loved how you could convince people down the line even if they said they had no time earlier. I was able to reach this large group of people in one square right before the time ran out, and it was just this huge sense of accomplishment. Ended up with 123 protesters at the end!
Good idea to include the time limit: it provided a solid end to the experience that feels better than forcing the player to collect *everyone*. Also introduces a sense of urgency. :)
Like others said, kind of wished there was a sprint button when backtracking/trying to find the remaining people. Also the game would occasionally lag, missing a beat. The beat was always in time with the music, though, which I understand can be deceptively tricky in a rhythm game!
Overall fantastic job. This was a great game jam game.
