Very nice!
I was a little confused by the mechanics at first, wrongly thinking I had to move the frog (I also completely missed the first 'door' disappearing.. I think maybe I blinked!) :D
But after a couple of minutes I figured it out and understood the potential for the mechanics. Really interesting idea. I especially like those double-jump puzzles where you need to time your moves to bring the key/leaves/etc into the lock. And the use of dashed lines to show which button will open which door was very helpful for trying to figure out the puzzle before you start 'tonguing' everything xD
Nice work!
