Hey, thank you so much for following my work and for the supportive words!
Regarding the animation style, I actually had to change it a bit. The animations in Chapter 3 were done frame-by-frame, which was extremely time-consuming. If I were to make the same amount of animations for Chapter 4 using that technique, the production time would be much longer.
So, I decided to use Spine (animation software) for Chapter 4. It allows me to animate the images without having to redraw them every time.
But don't worry, my goal is to blend these two animation techniques. Unfortunately, doing it all by myself makes it very difficult to keep it strictly frame-by-frame.
In the future, I plan to do everything frame-by-frame, but... I'm not quite there yet! Hahaha.
