This is excellent. Really high level of polish - I love how after a fight the gold stars let you know it's safe and draw you to turn the page. Very cool sprites that made me want to pick up and cuddle the cat.
Yes, the enemy variants need differing AI to add variety and challenge; perhaps you could have cut back on some of the enemies and spent time coding behaviors. But this is a pretty minor point.
Just kind of magical following a story through on the actual page.
