Really poor optimisation, it's as if you didn't even try at all. Trimming all the empty space from the drum samples and downsampling them already reduces this module to 11kb. Why even make chip music if you don't bother to chip it at all???

it's probably a huge waste of time to optimize a bunch of space you don't plan on using in the first place

I see that when I downsized my samples from using MilkyTracker App (Android OS).
