The concept of climbing the rankings by creating your own music through color-coded instruments is such a genuinely unique and creative idea — the combination of colors and beats coming together is really cool and satisfying when it clicks! The moving background effect and the overall art style give the game a really nice visual identity. A clear tutorial explaining the mechanics step by step would really help players unlock the full potential of the experience — once people understand what's going on I think they'd find it really enjoyable. The audio design is clearly a real strength here. Submitted with 27 minutes to spare — great work! Feel free to check out my sky platformer too 😊
