Again, I am here to give you a mini-lecture.
Touch is perhaps the most important thing.
There are quite a few fixed opinions about this matter, but leaving that as it may, I'd like you to think about as objectively as you can. As you can see, this is how the keyboard is laid out. Seen from the side, I think most people play the piano by pressing down vertically from above. But that's a completely strange thing. You could also touch them at angle, like this, instead of from above.
