Super cool, nice twist on the classic pong with cool art. All the unique ideas truly evolve the game past pong, and I'd love to see where it would end up with more additions!
The cover art looks awesome btw!
My only real suggestion: Why not local 2 player? it would certainly fit in with the game and shouldn't be too hard(then again i dont know the code so maybe it is)
Then the controls for swapping are certainly something, not that bad when u get used to them, but number buttons or scroll wheels would be a better choice imo(im sure u had ur reasons tho)
Anyways that's all from me, your game looks awesome and plays smoothly, good job! you should be proud!
