Ok, let's see. I definitely appreciate the slightly different approach to story than most other games here have - I swear I'm still dreading that suddenly MC's younger and older sister, not to mention hot mom, of course, will appear and reluctantly fall in love with him...
I love the models used for characters (well, except the one for MC but then again, modern alt/indie/emo "rock" *spits on the floor* kids do tend to look strange to my eyes) and their personalities as well. I personally hope I read the situation correctly and that Selina's mother will join the party next time.
Also love Jane and Lisa, so I can't wait to progress their stories as well.
Now, regarding the language, truth be told, after seeing a few reviews here I expected it to be worse but it's actually not that bad at all. It is perfectly understandable, it's just the slightly strange sentence structure or unusual word usage every now and then that gives you away. You should definitely consider getting an editor for it though. Personally, the "Depraved beast!" gets me every single time. XD
