First, we want to say, Awesome job! As stated below, it has a really nice game loop, which makes the game addictive. The pixel art is really cute, and the color palette is nicely chosen. The sound effects and music fit the game perfectly. It is a really cohesive game. It would be awesome if you included a leaderboard after the jam is over. Also, sometimes when cars collide with the frog, it is not taking damage. Keep up the good work!
