Since this game is part of a series, I first created mp4 file on the following page as a video.
https://dindindindin.itch.io/akari-syokusyu-en
https://dindindindin.itch.io/kiritan-vs-tentacle-monster
https://dindindindin.itch.io/seika-vs-tentacle-monster
and this page updated too.
I hope it works well...
