Toad Runner (Prototype)

Personally I do not care for the concept. The frog is a bit unresponsive, like it takes a few extra frames for it to move. I appreciate the choice of questions you are asking when it comes to feedback, which leads me to assume that you actually do want to make something good or that you could at least feel proud of. So here is my suggestion.

I would suggest not worrying about details like car speed, and lane generation. As it is right now, the game is not all that interesting. In fact I am fairly certain there is a game on mobile like this. However, if you are willing to incorporate it into your game, you can incorporate these ideas into your game:

Maybe add some extra abilities that the player could utilize, you could let them choose between two abilities in the grass area between lanes. Abilities like, hoping over two lanes at once or being able to take a hit from a car. You could maybe do something to slow down time, maybe even jump over cars.

To summarize: The game feels pretty bare bones and needs something else to make it interesting.
