4.2
The first one would be the translation: It's FULL of typos, starting by how Seilan's name is not properly capitalized, how some names are not correctly formatted into the dialogue box (creating weird spaces between names and other words) and the english in some parts is... Questionable.
You CAN, and WILL be able to, understand the game and it's plot, but it will be really noticeable that some things are not properly done.
Secondly, if I remember correctly in the JP version you could choose your first Alice out of the main three. They gave you the option to get Sakura, Margaret (whom I believe was named Margherite) and Iris. The prologue was, iirc, playable. In this version, they default to Sakura AND the whole prologue is a video that goes *way too fast*. It's difficult to catch what they say, to be honest.
And finally, the last problem is... they added ads. Even though they are fully optional, some of the screens have got some very annoyingly placed "Ads" buttons, which honestly just... look ugly, out of place and annoy me www
But all in all, it does seem like a really good version, so I recommend wholly to give it a chance!!
