It's finished for now. I'm trying my hand at making some smaller games that I can finish in a few months. If this is received well, I might make a follow up game set after the ending of this one, but it will depend on what my patrons want.
Length of visual novels is fairly dependent on how you play them. If you hold skip the entire time, you'll get to the end in about 2 minutes. If you take 5 seconds to read each dialogue box, it's probably between 2 and 3 hours.
If you stop to "inspect" certain images/animations, that will obviously add more time as well.
