I guess you can call this style “Slab Serif” - due to the squarish and blunt serifs. I actually was inspired by well-known designs, such as Rockwell, Geometric Slabserif, Calvert and alike. But decided to make this font more wild, cheerful, organic and unpredictable.
The edges are rough, lines and strokes are thick, serifs are sometimes missing, placed wrongly or maybe even missing! The result: A super legible slab serif font with a twist of comic and graffiti!
