Awesome! That's so cool! I love your pixel art and music effects, and the interpretation of the wave is spot on! This pixel art brings back memories of playing NES games as a kid. I love it! Even though it's a little blurry at times, it's still fantastic! The overall quality is also very high; I think you guys are a very professional team! Well done!
My only suggestion is that perhaps the main character's colors could be made more vibrant, making it visually clearer if it's distinguished from the background. Also, adding some checkpoints would make it easier to retry difficult parts and avoid repeatedly running through the map.
