When i played it, i was like "Its a really good subversion of Pong!"
Yes, the mechanic is defined and the puzzles are pretty, but there is a bug where when i finish the second level it starts the second level again, so i don know if there is more, but you gave a really good impression!
You should practice puttin sounds in unity, i know it is hard to learn during a conquest, also play test even if you are tired so there wouldnt be bugs like this, so that's my both tips.
If there is more levels, you can upload the fix, but if there isnt, you had a solid idea and i like that
