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 fucked 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 !
