Hey i recognise this game mechanic ! Were you inspired by Ori and Will of the Wisps ?
It's a great mechanic, and I had fun playing through the whole game.
Maybe having more of a momentum when you exit the earth could make the chain burrows flow even better.
Also the air jump felt like a bit of an illegal double jump, since you can only do it if you have not jumped earlier. Maybe allowing a classic double jump would make it more intuitive.
My last nitpick would be the end level screen, Having the "YAY" and the "OOH" for the time medals you won was funny, but finishing with the "oohs" made me kinda end every level on a feeling of failure, even if i had one or two medals.
Anyway the bee with the realistic face at the end was hilarious, I had to take a screenshot. Really the highlight of the game.
