Interesting twist to an otherwise very simple comic strip. I think the part where the protagonist flies into space was pretty nice. Not 'THE GREATEST THING I'VE EVER SEEN!!!!!!', but still unexpected and better than the original,
This is because he only has one frame tweened around during the entire sequence (just after he pushes the lid over the well). As someone who used that trick extensively in my first year of making cartoons, I find it to be an astronomical time-saver (no pun intended). Not that it saves much since your jump from comic to animation barely go over 15 seconds, not counting the new ending.
SUGGESTED IDEAS:
Link the original comic in the description. Trying to find the original comic you based this animation on was very difficult since I have to skim through 160+ of them on your website just to find it.
(For anyone asking: it's comic #48: Well. https://bigfootjustice.com/comic/well/)
