Interesting flip mechanic, and the dithering is top-notch. It seriously looks interesting and stands out visually.
That said, the flash of white screen when the primary level composition kinda hurts the eyes a bit, so watch for that.
Also couldn't figure out how to leave the pit if I fell in so I had to restart a couple times...not sure if there's a way out and I missed it or if it's just like that because it's unfinished.
Very neat starting point, can't wait to see it completed.
