Nice concept, but more development would be advised. Still, I got my established goal of 500 points :D.

The sprites are nice, but why the frog always turns to the right when standing? At least, let him stand in the direction it last moved. Also, maybe a working animation would turn out the player's experiment better, just commenting.

For such a huge road, it takes a while to be filled with cars. Although after 100 points, there is a wave of them! So, maybe a little more control on the number of cars would probably be nice!

Nice work!

This was a cool idea. i do wish the cars got faster though. potentially waves, like at some point it goes back to only a few cars but now they are faster, build up the traffic again, then reduce to a few cars and speed up again. just for a change of pace and increasing difficulty. Had fun with this one though!

Simple fun and good sprite art!! :D

A cool little game! The difficulty ramps up a bit slowly, but that's a fairly minor critique. Some unsolicited advice if you don't mind: When you release the arrow keys, the player always snaps back to the right. You can fix this by only rotating the sprite if there is player input. i.e

if( Input.GetAxis("Horizontal") != 0 || Input.GetAxis("Vertical") != 0 )

{ 

    // Do rotation

}
