Before creating more levels, I'm focus on gameplay on a single test level.
I note your suggestion about the pollen, I will change transparency.

here's the power'up list:

Name/power1/power2/power3

Multiball/ 1 ball/ 3 balls/6 balls
Laser/ slow/average/fast
Cleaning Ball/small zone/ average zone/drop a cleaning plant
Explosive ball/1 time/3 times/6 times
Kamikaze Ball/Stay 5 s/ 15s/ 30s
Multiply score Ball/ x2/ x3/x4
mosquitoes Ball: 3 mosquitoes hit mobs/ 6/ 12

Now the list for bricks:

Attractive : ball direction change near these mobs
Magical : ball is teleported somewhere
Spitting : they spit moss around there location.
