Great melody, but a bit muddy
First of all, it's a great arrangement and the tune is insanely catchy. However, just because it's retro doesn't mean you can't mix a little! All of the sounds are clashing together into a huge mess of noise, which doesn't sit well on the ears and distracts from the rest of the song. Give it a little volume mixing and especially focus on panning some sounds away from the central point.
5/5, 8/10
