Hi, LoveSickBee!
I'm flattered that my VN inspired you and I understand too well about being a broke college student x'D
I really appreciate your support tho! No matter how small, it's the one thing that keeps me up--I'm really self-conscious about how I'm a lot slower compared to other gamedevs so I'm honestly touched to see people are still waiting patiently QuQ you guys are Saints!
As for your questions: I'm using Ren'Py for programming and Photoshop/SAI to make the backgrounds, GUIs, and sprites. I hired someone to make a few original background musics for me, but most of Bermuda's BGM are made by Alcaknight ^.^)b he is a great composer! You can find him at soundcloud! As for the rest, I looked up various websites such as freesound.org for the SFXs (make sure they're licence 0 if you plan to commercial it).
If you're planning to start learning Ren'Py, I recommend looking up a website called 'Lemmasoft'! It's where Visual Novel developers gathers and shares their work ^.^ but most importantly, it has many tutorials! Both for beginner and advanced!
Last but not least, thank you for participating in the Q&A session! I've taken note of your questions~
Don't hesitate to ask me if you have anything else to ask!
xoxo,
SweetChiel
