I really liked the atmosphere, the pixelart and the game idea of having a maze you quickly have to traverse.
Also I liked the rabbit that once caught gave you time back.
As someone else already suggested, an input buffer system would be great.
My move inputs kept not being registered cause I pressed a key during the movement of the frog.
Also maybe interpolate the movement of the frog over time when he moves a tile so its not just an instant jump to the next tile.
I think that once the frog movement feels a bit nicer the game will already be drastically improved
