This is a very interessting concept.
However I must admit I did not like the controlls - I never felt like I was in control - always getting pulled to the left and when I wanted to break out I overshot - which made avoiding dark matter and getting what I want rather difficult. Sorry :/
PS: I don't know if this is an unreal problem but my AntiVirus was not happy with your game and made a 10min test before it said " you know its fine"
