This is a game by Przemyslaw 'Rezoner' Sikorski that I came across on Google+ and I've got to say it's amazing, he created all of the graphics and sound effects himself and coded most of it on his own in HTML5 all in around 20 hours and I've got to say I'm a fan (bonus points for the very chill chiptune music).

You can play a demo of the game here (it's seriously amazing).
_{Also try it out on your iOS or Android device, it supports touch screens.}
