I used to read comics regularly about 5 years ago. I came back to revisit my old favorites and was surprised to see how much Heart has changed. If Mr. Tatulli is reading this, I think it’s a great idea how you change your strip every few years. I think comic strips are dying because of cartoonists’ fear to evolve the medium or at least their own creation (such as aging the characters). I like your risks. It makes your older strips feel more nostalgic as well. Aging Heart brings so much more new storylines to the table, while being the same old Heart.
I know it’s your character and all, but just please just don’t age Heart any further though. Because you’d have to mention all the things that come with a girl her age and just… no.
