This is indeed a brilliant game, where I just want to thank everyone involved in doing a brilliant job.
The designs and animations look and work nearly perfectly with a very wide-ranged and customizable collection of looks and clothes
The story and writing is wonderful , making each character unique and memorable
The gameplay öh..worked. I find it hard to rate gameplay in a genre like this, I'm sorry, but it didn't annoy me, so it was good^^
Oh and the small things...this little references, that let you smile and respect the devs like Snape hearing a 'mysterious ticking noise' or Tonks' Hair getting red each time Snape calls her Nymphadora, because she hates that name.
And most important: The notification, that you reached the end with that character!! Thousand thanks for that, going that extra mile to spare the players wasted time! Every unfinished game should have something like this.
It was nearly bugfree, I had one error-message after the quidditch-game I could click away and after that Cho came in the office naked instead in her party-outfit (which worked completely ok in the workshop after that) and some small placement-bugs with the chibis. One time after BJ Luna stood right in the table and one time Genie was shoved and landed in the left wall, but that's it.
The only real criticism, that I have is the clunky way to get money. The System with writing reports is fine, but you only get payment for it every 7 days, which is a lot in this game. Same with the percentage from the weasley's shop.
If you need money quick, like to buy a gift for an angry girl, there's no option but to send hermione working, which
1. she needs to be in the mood for.
2. You need to have bought the necessary costumes for
3. locks Hermione out of other actions for the whole day.
which is not perfect.
I still give it deserved 5 stars, the main point for those games are, that they entertain me and arouse me, and it did both easily^^
