Hi, MaiHarashi!
You're welcome and thank YOU for giving Bermuda a chance! I'm really flattered to hear you've been inspired to make your own games due to playing mine! ^///^
There are so many things to do in order to make a visual novel, but I do have some advises to share:
1. It's important to know how a story starts, the middle, and how it ends. You might want to make short notes, depicting the order of the scenes.
2. Commit to making progress each week! It doesn't matter how small, just don't stop. Little by little, polish it, give it your best so you won't leave any regrets, and you'll finish it before you know it ^.^
Good luck and I hope to see you around!
xoxo,
SweetChiel
