Thank you so much! Yeah, I couldn't figure out that annoying bug in time. I tried a few things to fix it, but then I had to prioritize other things to fit the schedule. Supposedly the AI player should not "forget" about balls with low x velocity regardless of the direction, but there must be something overwriting that. I also wanted to snap the ball to a fixed number of possible directions removing the more "vertical" ones, but again it went to the backlog. There's also an issue with the AI player chasing the balls from behind: the actor tries to position itself in front of the ball, but there is no pathfinding, so chasing from behind ends up in them being stunned multiple times! :D
Thanks for reporting the bug and for taking the time to give this game a chance to entertain you.
Cheers
