Well done! This is a fun little blast of nostalgia. The game is more aesthetically pleasing than anything else, so good job on the graphics!
The gameplay was quite fun too! Shooting while playing Pong is pretty satisfying. Little things like how the ball can actually hit the tiny enemies and bounce are what turn this from "good" to "great". The different game worlds were nicely designed too, although I would've liked to see some more interesting mechanic variations between them. The ball did get stuck quite a few times after some dodgy bounces, getting stuck permanently bouncing vertically or horizontally at the top of screen.
Great work either way and thanks for the nostalgia trip! Would definitely play more of this if you expand upon it. Congrats on submitting 2 minutes before the deadline btw :D
