I actually really liked it. When I went to the game page, I thought it was another boring pong, with an interesting feature, but no more.
But you surprised me. It's a really cool idea to turn a familiar pong into a challenge with various unexpected tasks.
And suddenly, when at the end we are given just the freedom to play pong, it feels like a reward.
However, I was a little annoyed when a computer player suddenly started playing too poorly or too well, which interfered with the completion of tasks. But maybe I didn't fully understand the ways in which I can influence his behavior.
