Well, i tried the online version for the fun.
1) A lot of grinding
2) Not much content, and almost exclusive to Hermione (such a shame with all the girls in Harry Potter universe)
3) English translation is made with google, even me with my poor english i could do a better job
4) Dialogue are craps and pictures just don't match
5) The game is too much linear : Wake up - > Tell the truth -> Hermione -> Sleep -> Wake up -> Tell the truth ...
If it's HTML i still have some basics so if people is interessed we can try to remake this one...
Edit : I just realised it was made with Renpy but i really think this kind of game would be far better in HTML for obvious reasons.
