Enjoyment: It was really confusing in the beggining because wasd only moves the paddles but arrows moved both so I'm not certain what this game is trying to do. But I decided to try it with only arrows and it was actually pretty fun and hard. Another thing I noticed is that sometimes you started and the ball hit you right away which was very annoying. Also adding a score is crucial because if you do that it'll encourage people to get higher scores and play longer. Overall it was pretty enjoyable once I understood it!
Concept: I'm not sure exactly what youre trying to do but I think the controlling both with the same controls is really fun and challenging.
Presentation: Very simple but it works. I think the colors could use a bit of work though maybe try looking at lospec to get a palette next time. Also sound can really help with game feel so its pretty important.
Use of the Limitation: Nice because getting your snake longer makes the pong game harder.
