I still remember the good old times when i played this along with the other Mausland games as well when i visited Mausland before its gone.
By the way, i have a question about the music in the "Paradise" parts, like at the beginning and where you normally are.
What's the name of the music used there?
Edit: The music its called パーティー・ジョーク but its a bit faster.
I found it but in its original speed in Soundcloud: https://soundcloud.com/tadashi-kawata/wxrvu1i1hpgy
