Very nicely built for what it is. Advice I would give is to make the progress feel more rewarding; the repetitive nature of the game became boring after only a few lvls and the lack of reaction from the game made it all feel relatively aimless. Structure and UI are well done but in the future I would advise you focus more on making something about it engaging, even just a pop of confetti at the end of each lvl or the guy on the radio congratulating you would be nice!
Very cute, keep going!
