Yes, it's Pong; about as basic as it can get. Actually, maybe it's even simpler than the original Atari Pong: https://youtu.be/e4VRgY3tkh0
Sound effects are the first thing you should add – you don't need music, but it shouldn't be too hard to find a free "bleep" and "lose bleep" sound (try https://freesound.org).
Another thing is that you should add a lower limit to the bounce angle – sometimes the ball bounces in an almost vertical direction and it takes *ages* for the ball to reach the other side. Sometimes the ball is even launched from the starting position like this. See here:

To keep the game flowing, you should probably make sure the ball can always go across the screen in 2-3 bounces tops.
The final important the game could greatly benefit from is adding a computer opponent. You don't always have two players and I think you can find loads of examples on Pong artificial intelligence opponent on the Internet.
There's also no limit for victory, so the game never ends until you decide so. Ending the game when one of the players get score 10 seems appropriate.
Minor things:
– There's a bug with the score number disappearing (see in the gif).
– The separating line in the middle of the screen looks weird. The distances are uneven and the bottom rectangle is cut off.
– There's a typo in the menu ("Opitions") and strange spacing between letters ("Credi_ts", "Control_s", "Opi_ti_ons").
– The menu navigation controls don't make a lot of sense. You select with arrow keys and press space to confirm. You can't click. Okay. But in the submenus (Options, Credits…), you *have* to click and can't use space. It's inconsistent.
– Not to mention there's no need to add Options submenu if there are no options. "We don't have | Go to men– (the rest of the button text is cut off)" is completely unnecessary.
– You could use the menu font to display the score in the game. For consistency's sake.
It can be a good Pong game, but there's still a lot of space for improvements.
