Haha don't worry, there are some things, I hope they help you, and good luck with your game:

1- When moving the platform, you can see the png with a line next to it, so I guess you have to correct the image

2- The music is fine, but it must be in a loop, because it plays once and then the game is silent

3- You could increase the speed a little more if you want, it would be more frantic

4- I don't know if it's part of the game or a bug, the fact that in a certain way the blocks have "physics", so they can be stacked non-linearly, I don't know if I make myself understand, but what happens is that when the The block is already on the platform, but it can still fall over if another block bumps into it from the side, so it's like a Jenga tower. I don't know if that is the idea or your idea is that when it remains on the platform, the block itself remains static and can no longer fall

5- This seems essential to me if you want the game to be almost infinite, there comes a point where you can't stack anymore because the tower is very high, so the score is sometimes simply low, if there is any way to It would be nice if you could fix it, perhaps if little by little the platform was coming out of the visible screen downwards so that they could continue stacking without a problem, that is, that the platform goes down to make it more comfortable to play
