I really liked the 1st part... It's a pity that this part is so long in development (of course I understand everyone has their own circumstances), but it's pretty sad to see the game in development for 5 years with only 60 percent progress.
Even at 60% complete it's a MASSIVE game: I'm pretty sure each of the completed routes is at least as long as The Rose of Segunda is in its entirety. Honestly, I'm super impressed by how many routes we already have considering the sheer amount of work that must have gone into them and it's already one of my all-time favourite VNs.
There are games out there that take a LOT longer in development that aren't nearly as detailed as this one is. If you want to play a completed product then the only options you have are to wait for it to release or forget about it entirely.
"Current game word count 763,000 words"
A quick google search for average word count for a novel
"Between 70,000 to 120,000 words"
That's anywhere between 6 to 10 Novels worth of content in its incomplete status. Just some food for thought.
