Now I have it.
Tried Windows version. Game does look and feels nice. Shooting the enemy feels satisfying!
AI seems fair but I don't think I could beat him on higher speeds :)
One problem that I had was with my controller. Its left stick is a somewhat worn out and sometimes tilts to the left when released and your controlls code is a bit too sensitive for me and my paddle kept moving to the left. So I had to play with key board :(
Noticed A.I. has some "blind" spots.
Also one ball got stopped against the wall. AI also seemed confuder about it.
