One Way

Simple rules!
All you have to do is combine the two triangles. Nothing special, but you can do this in almost every direction! You only have to remember that they must have space in the middle.
If you do it with opposite triangles, you will create one of them in the middle. But if you connect the triangle with dot, both will disappear!
Player goal is to left with only one dark triangle on a straight line to the the Dark Hole.
If you can't do one level, you could use a hint! But be careful. You have only 10 of them.

Enjoy!
