Thank you for playing my game and giving a feedback!
I agree with both those statements! Fonts were chosen at the last moment and are definitely not good.
For the sprite size, I had so much work left that I decided to let it like this, since the bigger part of the blob indicates the hitbox place, but I agree and would definitely change that. One question I would like to know your view on, should the hitbox change with the animation or should the animation always fits the box?
