Hi
There is a similar course from GameDev but it focused on pixel art.
The course which I am going to suggest related to Vector Art and 2D Animation so we can work as 2D game animator as well.
Suggested topics in the course:
A. Vector art design with Inkscape (or similar free and opensource vector graphic application):
- background design
- character design
- UI design (Menu, Buttons, …)
- Props (Coin, platform, …)
- spritesheet and tilemaps
B. 2D animation assets with DragonBones (or similar free and opensource 2D animation application):
- Cut out animation
- Skeleton, Rigging
- Humanoid Animation
- Export to Unity
C. Unity 2D Skelton animation tool
Thank you
