I hope you'll check out this free game, previously an Android-only paid app, now free for you to enjoy in browser.
It's cute, fun, kid-friendly, and with a few surprisingly challenging bits as the game goes along. It also features storybook narration.
There are 2 different world types in 12 levels, plus a set of unlockable skins.

Fun fact: I enjoyed making this game so much that my dev label is actually this game's namesake ;)
Another fun fact: the original concept was a platformer I developed in GameMaker, before I ended up making this much more manageable type of gameplay, though I do want to revisit it again in the future.
