How To Use?
Once in a level, you will be able to press 7 (can be changed in settings) to pull up the Portal Gun or the Mirror Gun. Beware that equipping either gun within a level causes your score/leaderboard submission for that level to be DISABLED, once you finish the level you will see a text saying - USED PORTAL GUN to indicate the invalid run.
The Portal Gun
The Portal Gun is the blue variation, it allows you to shoot two portals using your primary or alternative fire.

The Mirror Gun
The Mirror Gun is the green variation, it allows you to shoot one big mirror portal using your primary fire. With the alternative fire you can shoot a mirror that flips the world upside down, how whimsical!

The Twist Gun
The Twist Gun is the red variation, it lets you shoot two portals that, upon entering them, rotate the world based on what way they face. It's confusing at first, but once you figure it out, it can be very fun to mess around with.
