DOT KOBO - KANAE ME AND MOM'S SUMMER VACATION FINAL

[Art-X]

Hey guys,
Am new here.
Who knows this game (DOT KOBO - KANAE ME AND MOM'S SUMMER VACATION FINAL)?

I'm looking for games that are similar (at least in content/story) to this one (Crystal Story is out, since I already know that one).
Who can help me with this? Where can I find such games?
I would be very happy about any helpful answer.
Thanks in advance.
