Well I really liked what you've got so far! I've been using a translator to get most of the words into English (as best as any of us can), so I was able to get through the game right now.
You've got a good story going on with this group, trained to fight monsters, and a good spread of who is most ticklish in which spot. You've laid out a bunch of evil characters and they've shown (in more ways than one) what they can do.
The game has been fun and hasn't been horrible to get through. Leveling up was good and the abilities I got (whatever they are) are also good. I was using a translator, so everything was kind of hard to read in battles. That's to be expected though, and overall I understood what was going on.
Speaking of battles, I loved the tickle attacks each enemy had with the girls. It was a nice bonus added on during battle that showed more what was really going on than "Enemy tickle attacks and this character laughs".
Also, Sasha (That was her translated name, the third girl to join) has been my favorite so far, but that's more so because her feet are her weakness and me, being a foot lover, am biased. The interrogation scene was probably my favorite in the whole game. Also, I REALLY liked the black book. Being able to watch tickle scenes OR refight enemies is great! Excellent work!
I hope you'll let us know when you update the game. I look forward to playing more and seeing what happens next in the story
