Attractio

Attractio is a fun indie first-person puzzle game, somewhat similar with Portal, where you need to use all your skills to manipulate gravity and solve every puzzle you come across.

Keep in mind that each object has its own gravity direction that can be changed using special gravity boxes. Momentum is also important, since you can change the gravity of a box and jump on it to cross a gap.

The game will also give you the chance to experience it from the point of view of three different heroes (Dalek, Keir, and Mia), who compete to win the TV show's grand prize. Also, each level is designed to be solved in multiple ways, so always be on the lookout for an alternative when you think you're stuck.
