Absolutely phenomenal presentation, minimalistic but quite well polished. The sound of the ball hitting the bat and the walls is perfection.
I will say there's not really much gameplay wise, though. It's pretty fun but not for that long. Personally I find it pretty good for maybe 2-3 sessions and then I got bored. The concept's also pretty generic, but it works well.
Very solid game overall though! Definitely an above average entry.
