Always a fan of pixel art, y'all did a great job on the overall design. It took a bit of experimentation to figure out how to play the game and how the game mechanics worked, I think a little popup explanation before the game starts would help a lot. The difficulty progression from train car to train car is good, but again, it took me a while to figure out the controls. The game mechanics and the way that you interact with the rhythm is creative and strategic, each room is a puzzle. The music is pleasant and the audio feedback is responsive. Your narrative is cute and the cutscene in the beginning does a lot to convey the story. I did run into some bugs when I tried to use the skip mechanic (K), and also there isn't a way to exit the game so I had to alt+f4 to close it. Overall, I really like your game, great job!
