Well done! I thought the song would get stale after the first minute given how slow it is, but honestly you developed the idea really well, each section reinvigorated the motif a bit more, that's not a given. I like how you used 13/8 and the transitions where the time signature changes a bit up are on point and interesting in their own way. The soundfonts you used give it some charm in their own right, but they sound pretty stiff, and do not really have a dynamic range, so in that department it does get kinda repetitive.
Still, in a videogame setting, it will likely fit no problem, great work :)
