ooo is that reverb or are you using the delay method where you replay the sound but in a lower volume? really dig that hehe

really cute song you got here if i do say so myself! i do feel like some instruments are a bit too dry tho, so maybe a bit of reverb wouldn't hurt. (like the flute at ;30-;35) you could also add a bit more instrumentation at ;52-1;27 to make it more full, it does feel a bit empty with the main melody and the chords only playing there.

otherwise, i like this!! tell your friend some random stranger on ng says good luck on their game! ;)))))
