Thank you! I'm glad you enjoyed it and it even inspired you to create more visual novels! I saw that you already created one and so I played it, I'll leave a comment on your page soon about it, but overall, you already did a great job with using renpy! Your UI design and the art looks great!
I'm probably not the best person to ask about renpy since I only did the barebone of designing and scripting/coding, I honestly still have much to learn. But a tip from me would be to create backups of your project often, just so you wouldn't lose a lot of your progress if something bad were to happen (I usually create mine in google drive. I just copy and pasted the file there ). Another tip that I have is to visit lemmasoft forums for renpy questions, the renpy discord server, and watch youtube tutorials (for YT, Zeil Learnings' channel really helped me a ton and I will never get tired of recommending that channel to people who's trying to get started with renpy). Make sure to leave notes in the code too so when you can understand what you just did (the lines that start with #).
Hopefully these tips could help somehow! Excited to see more from you as well! :D
