My wrists are super sore and my fingers hurt because I've been mashing the keys so hard for three hours. This is WAY more difficult than Portal, and takes things a step beyond. Split-second timing is the difference between success and failure, and you'll have to use superhuman reflexes to beat the best times and top the leaderboards.

The gravity mechanics are fantastic and force you to plan your routes in advance. Tethering balls and double-jumps help you navigate this first-person puzzler and it gets EXTREMELY difficult as the game progresses. This is not for the casual gamer, it's for challenging yourself.
