What???

Version 2.10.4 - Mar 11, 2012

Bought this long ago on my iPod touch and loved it. Just installed it on my new iPhone and it wants $2 to get past the tutortial? Bought it once I'm not buy'n it again. 5 stars for a great game minus 4 for being greedy.

Very good challenge

Version 2.10.4 - Mar 9, 2012

Can be a bit frustrating with how fast the upper levels hand your rear end to you, but makes a win more satisfying.

Gravitational...

Version 2.10.4 - Mar 2, 2012

Very good intrinsic knowledge of gravity and vectors. The detail and formulas used are in depth and amazing.

Ripping me off!!!

Version 2.10.4 - Jan 5, 2012

Already bought and paid for the full game. Now they want another $2?!? That's garbage. I'm not paying twice for the SAME THING!!!

Good game

It's good

Version 2.10.4 - Jul 11, 2011

The game is great, the price is a little large for an app game but for me it was worth it. The Steampunk styling is awesome along with the gameplay, it is quite challenging too.

I love this game
