Stop me if this sounds familiar. Imprisoned within an enclosed facility by a disembodied female voice, you re given control of a prototype weapon and led through a series of physics based puzzle rooms which… No, it’s not Portal.
This is Magnetic: Cage Closed [official site]. Which seems very similar in a lot of ways, except for one; there are no portals. Instead, that untested gun in your hand allows you to control magnetic fields. Now you re thinking with Magnets. Hmm, come to think of it, that sounds familiar too…
