Thanks for playing. I'm glad you enjoyed it. It was very time consuming to build to this standard so there is only 1 level. I may add more levels in the future though.
The balls are spawned at random yes, so you may be lucky with what you need and you may have to wait longer.
PS. that's a good high score 😁 also congratulations on not losing a level. I've never finished the level with red level still there.
