Sloup4831. Is this really your first game?
I'm asking because it is by far and away better and more engaging than my first game ever was. The timing of the ball, the gentle slope of the difficulty curb, and highly readable/expressive animation of the frog all stand testament to this maybe being your first game, but definitely not your first design of a game. You've been thinking about game design for a while, me thinks.
Nicely done! I was quite addicted to pushing for a higher score.
Hey, I made a game called Juggle last month where I did a kind of similar thing to you here (definitely not the same), and at the very end I decided on a whim to add text dialogue in the center of the screen that progresses each time you hit the ball. I found it really rewarding writing a story into a game that otherwise would have none. I'm wondering if it inspires you towards anything?
