Sine Mora is a bullet hell, side-scrolling shoot 'em up. It looks gorgeous, has a really in-depth storyline and is so much fun to play. Being a relative new-comer to the genre I absolutely suck at the moment but there are various difficulty levels and game modes that mean even novices will enjoy the game.

Just wanted to mention this as it seems it might have gone unnoticed by a lot of people and at £8 it's an absolute steal. Go buy it!
