I like the artstyle and the music! The concept is also interesting!
I would suggest adding some camera controls as sometimes it is hard to see some things in a few levels, also you could make it so the player moves when we press only one key rather than first aiming the player and then pressing spacebar to hop. You can bind the keys to aim the player to some other key if aiming is important for the tongue grab, like WASD to move one tile, and IJKL to aim the frog without moving
