I think for me, it more made me realize that I need to stop stalling learning more complex visual design features, which is something that I've kinda been afraid of.
This is my second game jam doing it as a full time artist, and I feel that my art always ends up looking a little dlat. I like working in a low pixel, limited color palettes art style because I'm not confident in my ability to quickly make art that is more complex than that, but I think I need to learn more about shaders and particles to make my pixel art to go from "pretty good" to great.
This really stuck out for me when I played I Return Stronger, which literally just had a square and simple shapes, not to mention had the same core game idea, but looked so much better because it used a lot of shaders and particle effects.
