I only played the first ~quarter(?) of the game, but bear with me. This covers my feelings of the game as I have experienced in that time, and I have good reasons as to why I did not play further before reviewing.
(Edit: Apparently I was at the end of the public build. I was not aware of this at the time of posting- game file size fooled me into thinking the game was longer. Apologies.)
I'd say this is a great game, but sadly I can only say it's good. Unfortunately, the english is incredibly poor, making the game more frustrating than it should be to play through. I felt a lot of the events taking place towards the beginning weren't given much pretext, making a lot of it seem rather sudden.
I also noticed the scar on MC's chest is on the incorrect side when compared to the CG showing the wound. This isn't a big deal, but once I noticed it didn't stop bugging me so I thought I'd mention it.
Overall, the characters are a solid 7.8. I just can't give them a smooth 8, as a lot of stuff they do seems (again) rather sudden at times. Some characters are very forward without obvious purpose or reason, and you could say this is just the characters themselves or me not being deep enough into the story to know yet, but it soured my time reading to the point I didn't want to progress as much.
Once again, this is just my experience with the first quarter or so with the game. I'd overall give the game a 7.5, but I feel if these issues were addressed it would be a solid 8.5. The main problem I had was with what I could only assume to be translations. Those alone made me quit before finishing. Again, overall good game, just not as good as it could be right now. Better translations and characters would fix everything I found for the most part.
Looking forward to continuing in the future!
