"DRAW TO COLLECT"
Your main goal is clean the field!
And for this goal you have a black hole that vacuums everything.
But you have a bigger advantage against cubes. You can draw arms for your black hole to collect more cubes.
Just draw a shape that you want to use as arm.
To move your black hole you need to sling shot your black hole on the cubes that you want to clean.
You can give direction freely.
You can change your drawing on the way to better collect action.
And don't forget; you have limited move to collect them all!
