If you still haven't spent any quality time with Grasshopper Manufacture's steampunk shoot-em-up Sine Mora, pay attention. The game, which was already playable on Xbox Live Arcade, PlayStation 3, PlayStation Vita and PC is now also released on iOS.
If you'd like to save your progress or access in-game leaderboards, you'll need to provide your Facebook details. The US$5.99 download requires iOS 6.0 and above, and is not optimised -yet- for 4th generation devices). While it is available for iPhone, iPad and iPod touch, we're hearing reports that the new Sine Mora may not run in full-screen on iPads.
We'll keep an ear out for any updates on this - it may be something that's simply fixed in an update, but at this stage publisher Digital Reality is keeping quiet.
