The ducks are super cute! <3
The rest can be improved, I'll leave you a few suggestions hoping you don't mind:
- the controls aren't great, and in a runner they should be perfect: you should die because you did something wrong, not because you knew what to do but the control is quirky
- the gameover screen appears suddenly immediately after you die. I'd rather wait a bit, or it feels stressful. At least, it does for me.
- there are MANY runners in the world, and competing with them might be an arduous task… what about doing something different? Like, having ducks strolling around as calmly or as fast as they want, for no real other reason than they're ducks and they can do it? Like, you know, a lightweight duck simulator.
