I call that a mindblowing intro. Maybe even one of the best in the game jam. Its sketch art was also convincing. I missed the core gameplay in the game itself though. The idea with the walkman was awesome, but the feeling and presence of the walkman were not there. The level was very detailed with many elements and objects. I could also recognize that the UI had received a lot of love. But I would advise for the future to focus on a small core game concept for a game jam because it happens very often that a small game with a great idea creates a lot of fun. My congratulations on your submission and keep up creating games!
