So this is definitely a very intersting and innovative concept. I liked the idea of having to switch my music quickly a lot and it made for very interesting gameplay, as I also have to juggle my spotify playlist outside of the game, while playing the game itself. What I found is that it's kind of easy to find music that satisfies all frequencies relatively well, which makes you kind of invincible :P Also, I sometimes found that it was quite hard to know what was going on in the other rooms, even with the status panel in the top right, which meant that I sometimes lost the game without any clue of where I went wrong. This could maybe be solved by putting everything in one room, so you get a better overview? Anyway, very cool concept and I think you guys definitely learned a lot, which the goal was, so good job!
