The ability to move and resize portals adds a unique and strategic layer to the gameplay. The levels are well crafted around this ability and utilize the portal mechanic in very creative ways and offer a lot of rewarding challenges. I like that you can move platforms and enemies with the portal and the portal looks super cool and works perfectly. The last level was a little overwhelming to be honest but it was fun nevertheless. I also really liked the way the doors opened and closed as they teleported the player to the next level.
