I just have played the game once: not solving the case!
I won't attempt to make the standard mystery game where you're not really solving the mystery rather than it on folds in front of you or as the story continues. I'd like to try a different style putting the player in complete control of the investigation. They will be given complete authority to look into the case as they see fit and it will be up to them to piece together the puzzle and solve the case.
Reading this created big expectations within me, I have to say. However I felt the "case" rather unfolded in front of me. Pretty much in the way you said you would
not be doing it...
I hit on one girl rather than asking her about Natsuki, so I seemingly got only the choice of 3 bad endings o_0 I did not seem to get any chance to change the course after I decided to hit on the girl!
I was anticipating the moment were I could get out my list of names and see it. To chose who to ask and what to ask them and then making check marks. This
"complete control of the investigation" you said you would give... but it never happened.
I furthermore felt that none of the (rather arbitrarely) accused girls was really suspicious. At least not in the path I chose. Every girl appeared only once and the only clue seemed that two of them went to the locker room. As a player I wasn't really picking up (m)any clues at all.
Do you know the game "
Cluedo"? There was also a Commodore 64 game called "Killed until dead". Combining ideas of their game play with your story could make the investigation less linear.
Tip: if you turn the Wav files into ogg/mp3 the download will be about 15MB not 60MB.
I find the idea of a Ren'Py mystery interesting. There is much potential. Maybe you want to make another one with more control of the player!?
EDIT: I played again
and then looked at your script. The choices "to solve" this case do not really base on investigation or clues, but only if you try to get money from Nanako and not hitting on Sakuya... Checking for the lockers myself would be ruled out if I would ask for money from Nanako. Not really ~that~ elegant for a Mystery.
