Thank you for playing the game.
About the flipping of direction, my idea was that the level appears mirrored when you try to move to the left. The point lights that show up when the level is flipped is supposed to look like as if you are viewing the world through a mirror, but I can't seem to get it to look right.
I see your point about the 3 buttons. It simply didn't come into mind since I got used to the flipping being tied to the player's velocity. My playtesters didn't seem to mind as well.
If I ever make this into a full game, I will include that option in the accessibility settings, as well as tweaking the player's acceleration. Thanks again!
