THE NOTES GO AT LIKE 30TPS IN PIANO TILES 2. CONGRATULATIONS!!!!!!!! Lol seriously, I also really love how the song transitions from C# minor to D minor to D# minor and ends in E minor at the end.
Actually my bad, Aragami EX is harder. There's a list here, but thats for 3.0. not sure if any 3.2 songs are more difficult. Parodia Sonatina Var ii EX and ANiMA EX are 2nd. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-iuDZuz4PbdI.html
