Hey there, sorry for vanishing. I was recovering from an illness and wasn't really set to do the whole Internet/computer thing for a while. Still, I'm sorry for not really updating for a while even longer than that month.
I took a bit of a break on it. Napple Tale is currently done with its first draft translation and Eien ni Hen is helping read some of the documents over at her pace. Slowly working Linda and another project of mine back into my schedule.
sorry if I'm doing a dumb question, but this game has some kind of time travel in the plot?
Yes and no, actually. If you're asking about the different A, B and C routes, those are all alternate timelines. Some characters may be married in one timeline and divorced in another, or a character will be dead in one and alive in the other two and so forth.
Route D is simply a time attack and there is no uber-dedicated storyline in C. It's all just a bunch of sidequests for both random NPCs and characters you met along routes A and B.
C is mostly a really fun departure from the other two, but for all intents and purposes, I believe it to be the canon route of the story, but you won't nearly enjoy the jokes and references or catch the minimum amount of animals in time without playing through Routes A and B first. You also see some closure for some of the characters that didn't get any in Routes A or B. Plus, there's a difficulty jump in each. If you catch *every* single animal in Route C (which is pretty rough and I don't want to do it again anytime in the near future), you get a special epilogue exclusive to Route C that is really just a bunch of text, but it's really one of the most heartwarming parts of the game and wraps up the game pretty well.
That being said, there are some time travel elements tapped into in the game's universe in each arc, but I can't really go too much into it without spoiling anything.
I hope that answer was as helpful as it was verbose.
