Escape the falling blocks!

Cool game to enjoy, but here are a few things that I noticed and you might consider them to polish up this game even more, 

1.  The ball can bounce, which makes no sense as you need to dodge the block and that's it. So, it can be removed, or else add something that makes more sense of its existence. 
2. The ball is gaining velocity in order to move which feels really odd in games like this. The movement should be quick enough to test reflexes. 
3.  The spawning of the enemies is quite a lot making the game too difficult quickly which lasks the gradual increase in level difficulty. The difficulty of the game should be increased slowly in order to retain the users.
4.  It seems like you are not using the Object pooling method to spawn and despawn the blocks, which makes the game slow after a while.
5.  You can add various obstacles and collectibles to this game to make it more fun. 
6.  Also, the Game Over should be more impactful rather than just a text showing it and still the game running beneath.
