Sorry about the confusion, it shows the bounce order before the level, and also during the level on the right.
The numbers are the bounce number, and when it shows the explosion, that will destroy the target. The ui on the right reads top down so for example on level 3, it shows " 3 2 1 [explosion]", this means the ball will need to bounce 3 times and on the forth collision it will destroy the enemy.




Nice idea, and I was able to play a couple levels, but the ui doesn't seem to scale correctly for the screen size of the web build.
