This is really, really, great. I really like the pick your poison of choosing what obstacles you will face. Rotating the level is a bit mind bending at first but really fun when it clicks. You can almost bounce off the wall to land back on it if you were viewing the level in a non-rotating reference frame which is really cool.
I think adding a choice between 3 power ups every now and then (instead of obstacles every time) would be a huge boon the game play loop, creating a difficulty curve that ramps up then relaxes to give you time to breath.
Really great entry, my best score was 243.
