I really liked the idea. The blob is so cute and its animation is really fun. I got slightly confused by the score UI as some of the text overlaps the black wall and is hard to read. That can be easily fixed by adding a rectangle behind the score text. I loved playing the game. It's great aesthetically. I felt the blob moves slightly slow. You could perhaps add a sprint feature to the game, which allows the blob to move faster if some key is pressed.
