Hey, this is pretty clever. Really intuitive and fun ! I like simple mechanics like this one !
Random feedbacks:
_At first, I thought that clicking was freezing the racquet, but just for 0.5 seconds. It took me a while to realize that the racquet was unfreezing because of the ball touching it.
I ain't sure how to fix this really. Actually you already added the "snowflake visual feedback", which is cool. Anyway, after a few tries, I understood. Doesn't really affect the experience, 'cause you can retry super quickly.
_ Sometimes, I clicked just after the ball touched the racket. It was very frustrating because it wasn't moving, and it felt like it should.
--> "I did'nt click for you to stay in place forever like this, stupid game !!"
The problem here is that the player doesn't have a lot of controls and lot of ways to affect the game. He can't fix something he ****** up. If you do one mistake in this game (clicking without wanting it), you're gonna be a spectator of your death. There's no suspens. Once you made a mistake, you're just passively waiting for the game to kill you. Not really fun.
sooo, maybe a solution to this would be to add another way to affect the game (Although I love the fact that it's a one button game.), or maybe to make the player able to "unfreeze" the racket if he made a mistake. But it would change the whole gameplay mechanic so I'm not sure.
_Is there any kind of difficulty curve in it? Felt wrong for me on this point. I think the ball is just acting the same way no matter how long you played, am I wrong?
Also the game is really difficult. I think it would be better to start with something a little bit easier (if you can make this easier), and then have something like the ball speed is increasing or something.
Oh, and I scored 22 on my best try, if that's helpful for you
Anyway, the idea/the mechanic works fine. Improvements can be made, maybe, but it's really a nice game already !
