new opening (to me) nice game

I don't know for you guys but often you stick to a certain opening, yesterday night i was looking how my computer played against itself and saw an opening i wouldnt think of myself. Such openings can be nice to play how does this 'new' opening play, its always a bit strange to find out and go beyond path's you havent seen before, its like exploring. In my situation i played d4 e4 here is the commented game
