OMG I SERIOUSLY WISHED THEY SHOWED WHAT HAPPENED IN THE FUTUREE PLEEAASEEEE I CAN'T ACCEPT THISSS AAAHHHH
The animation was very nice though, I enjoyed it very much. The ending it very upsetting in my opinion, but I guess it does open a wide variety of imagination for fellow fans. So I suppose it's acceptable.
Although a continuation is still forever a silent wish within hearts.
