I think the game would be better if had a more precise control over the paddle - I didn't liked it sliding too much.

A high score feature is highly mandatory. Otherwise, cool simple game to pass the time, I think if you add some music it'll be awesome.

Good challenge value for sure

It's just infuriating enough to make me want to keep playing it. The addition of a high score tracker would be a huge feature. The difficulty is just right, but without a highscore feature it feels like I'm wasting my time. Mostly because I am wasting my time. But this game makes me want to waste more.

Oh, and another thing: Your Author Comment is missing the word "can" at the end. It just says "Survive as long as you !" Add can at the end and this will seem way more professional.

Really cool, LOVE THE SLOW MOTION
