Well said!
<spoiler warning>
I ended up finishing the 0.6.0 version, but I almost quit around the part the MC joined the gang. As you said, it doesn't even make sense that the MC wants to rescue his friend from his gang life by joining the gang and participating in gang activities. It's also bizarre that the MC seems to care so much about this dumbass friend when they only seem to have interacted together a handful of times before the big change. The gang storyline stuff is very painful to get through, and the characters are all completely unlikeable.
I also agree that Filo's overkill on the tsundere scale is hard to take.
I feel the game has a lot of promise, and the quality is good, but I feel like the gang stuff could be cut completely and the story wouldn't suffer at all.
