Hi Tobias
I know this comment is a bit late, since I promised to post one for like two months ago, but better late than never right?

Though it's nice to see that more people has been trying it out, after all it really is a great game!
I liked that you've enabled use of the mouse wheel for controlling the "force field"

and as it already told you I'm really thrilled about the idea and the gameplay itself (and of course the beautiful code behind it all

:handthumbsupR:)
But I think the game itself is a bit too easy.. I'm not at all sure but maybe if you made the movement of the player more "smooth", so that one would slide around more (like on ice or in space), and then if the movement of the player was always to be activated, and not only when one of the mouse buttons is pressed, i think you would archive a more challenging and thereby fun gameplay.
But I'm no expert when it comes to making great gameplay, so i don't know at all if that's the way to go

Also I've found a bug. When I was about to start a new level (I don't recall which one), I somehow, by playing around with the mouse wheel and turning around the player, managed to catch one of the enemies (before the level had actually started), which caused the level not to start at all :/
