PolarUP is a punishing climbing game. So you simply have to get to the finish by using your magnet powers.

Main mechanic
As you may know magnets have 2 polarities. Negative and positive.
If you try to connect similar polarities, some magical force wouldn’t allow you to do it. But opposite polarities are attracted to each other.
So the main tool that would help you complete the game would be a Magnet Gun.

By combining right polarity of the Magnet Gun and positive or negative charged platforms you attract/repel yourself to/from platform to overcome obstacles and get to the end.
But be careful! One wrong decision can cancel your progress and you have to start over again.
