Wow, that was super ! The quality sound is satisfying. Love the acoustic guitar, feels lively, almost as if it was improvised there before me. I like how you introduce the more energetic part at 0:28 with that sustain, and those cymbals.
The rythm on the drums is satisfying. The flute gives me Stardew Valley vibes and with the electric guitar, it reminds me of my childhood summer memories x). Nice way to go from flute, to electric guitar, then flute again for the ending.
You said it might sound too jammy, but I think it's what makes it beautiful, it's like sitting on a chair and people play it before you and you enjoy life as it is and it fits very well a credits roll too ! Could listen to it, eyes closed and enjoy.
One small thing, maybe the ending could have been extended for a few 2-3 seconds. Like after the final note, having the acoustic guitar play some notes in decrescendo, as the music is already sweet. The final note feels a little sudden.
Overall, it's one where I enjoyed the most listening in this jam !
