Gravity Hook HD by Semi Secret Software is not for the feint of heart. One thing Semi Secret seems to excel at is managing to make a simple concept work perfectly as an addictive title, but unlike Canabalt, you're going to have to work hard for your highscore in this remake of their classic 8-bit Flash original.

Your goal is simply to make your way up as high as possible and you achieve this by throwing out hooked claws to gain purchase on various orbs in an attempt to maintain your momentum against the immensely weighty gravity. Wrapping your head around and mastering the art of keeping your momentum active is not easy and will take some players (such as myself) a lot of time to feel comfortable with - and even when you do get a feel for things you'll start to beat your head against the fact that everything, including your hook-points are liable to explode and end your run.

However, while you're butting your head against the intense learning curve you'll be treated to Semi Secret's signature pixel-art graphics that are dark and moody while clearly conveying dangers (albeit at the last moment for some). The music is also fantastic and instead of long repeated tunes the music will shift as you pass various checkpoints, giving you a great sense of progress.

It's unfair to continually compare Gravity Hook to Canabalt, but the two games seem to represent two vastly different intended audiences and while some may easily slip in to the momentum-based gameplay, others will probably throw their iPhone at a wall.
