Woo this was difficult! Though it wouldn't be initially, seems to take a while for the ball to start noticeably growing, but towards the 50 points point it really is tough...
I love the idea, and the mechanics and visuals are nice, though a little strange you'd be hurt not just by paddles or ball but also by touching the borders of the screen itself. It does add to the difficulty though, which maybe is a good thing if you play it long enough.
That hundred point medal might take a while... after quite a few rounds I'm starting to wonder if it's even possible, I did get incrementally higher and higher with each attempt for a while, albeit very slowly, but after a while it's hard to get even one more point...
The square hit area of the ball makes it difficult to avoid, and there's little leeway with the borders when you fear accidentally touching those too. Feels like a liiittle less difficulty might be ideal.
Great game though. Difficulty curve maybe a little high.
