Thank you so much for your kind words about the game!!! Aaaah!!!!!!!!! We really appreciate the support and love, and we're super glad you enjoyed it fully <3! It makes us super happy to hear that our characters can have that much of an impact!!
As for the title track, I think I manually sped up this royalty free track: http://musicmaterial.jpn.org/new_music/tomorrow.htm
If you want the sped up version, it's here: https://sta.sh/0r3glbcr7ka (I hope the link works, but let me know if it doesn't!) :)
