Funny simple game. Gotta love to wonky unity physics.
Would have needed keyboard shortcuts for restart/try again or even making it fully mouse controllable. And as has already been said, the UI would need some finishing touches.
The camera could have also used some love. Both 1 and 3 were too far from the action (usually for me at least) so 2 was my favourite. Would have liked to see a more dynamic one that would be there in the action. Also, the frog started needlessly far away in my opinion. You had to do a 50% launch to even reach the road.
Super minor thing, but the small twitch the launch power bar did in the beginning annoyed the crap out of me for some reason :D
