My stance is that drawing new content already takes too long, so I certainly don't have time to go back and retread old ground 
I fell victim to the redo loop for like 10 years on one of my early middle school comics- I kept working on that same series that I conceptualized in middle school all the way until I was up and through university, redrawing and rewriting throughout but never really having much to show for it beyond like 15 versions of chapter 1. After I finally cut myself off from working on that project, I decided to move forward with my new perspective as described above.
This is not entirely related to the question at hand but related: I do think this is something to be thought about when starting a long series when one's art and writing skills still have a lot of room for improvement. Comics are an awesome way to improve both skills rapidly, but as a result it can leave a lot of newer creators unsatisfied with their earlier work- especially if the rest of a multi-chapter comic hinges on the opening to be strong. I talk about this in some additional detail in this video starting at 7:55, if it's of interest
(Again, though, it doesn't matter so much for an in-progress comic
)
For your comic, I took a look at the 3 or 4 first episodes and the 3ish newest ones, and I don't think there's cause for concern! You've definitely improved a lot, but the early panels are clear and easy to read, and that's the most important thing for a comic
the only thing I might consider editing would be implementing your newer font for the earlier speech bubbles, but the writing is neat enough to read without issue (for me at least) so even that's not really necessary~
(the only other thing to be careful about even in the newer episodes is semi-transparent speech bubbles. They're fine most of the time but can sometimes be challenging if they overlap an image. Generally opaque is the way to go, but it seems as though you mostly try to keep them in the gutters anyways which works!)
