I definitely lean more into their poses and silhouettes character design wise, but, the way they talk/personality is up to what I want out of that character. Like "A" would have a nice contrasting personality that helps enhance their overall character or make them memorable
For the 16 students that I already have designed, It was purposeful to choose Felix Amethyst you first meet other than the mc, due to fact he has one of the most unique designs for a stick person. In comparison, most of the cast have their own unique flare and it's shown in their sprites, and im VERY excited for players to see the full cast.
Thank you for the question. :)
