I really liked your take on the theme! It felt nostalgic, being stuck in a car and bored out of your mind with your sibling. I never annoyed mine by throwing paper balls at them but it was fun to do so in game. I enjoyed being able to play with the little handheld console too, those were the good old days eh? Unfortunately, the window game was unintuitive. I figured it out, but having to essentially smash yourself onto the ground before being able to "jump" a post was... weird and didn't feel good. I get what you were going for though, and I like the idea behind it. Oh and I loved the first music track! Very catchy! I honestly didn't want to change the radio station, haha.
I was actually disappointed when it ended, I wanted more things to do! Good work!
