Hello Shiro !!!. Just watched your video. I really liked it. I'm glad that at the end you thought about how the characters are connected and tried to understand how it all happened. And Yes. All three games are connected. But, now only "UNSOLVED CASE" is available.
The first part "DELIVERY FOR DR SHTRAUS" was too difficult to pass and contained a lot of errors. That's why I removed it for now.
BUT, if you play "UNSOLVED CASE" you will understand who BAM GLOVER is :)
Thanks again for your time playing the game.
