Loved it so much! I think experimental stuff like this is where we indie devs can really shine, because it would be just too risky for the big studios. Really takes one back to the earlier days where video games weren't these true and tested things and even big names in the industry just cooked up the strangest concepts.
Regarding the game itself, I loved the atmosphere,the story and the whole vibe. Reminded me a bit of Kairo. I actually would play a full fledged game in this style.
I also loved the weird connection of the screens and your eyes, had a surreal feel to it.
My only "complaint" would be, that the camera would not stop moving when you moved the stylus outside of the screen, so you could effectively just click the left screen, and then use the mouse as a standard FPS mouse-look. Would feel even more clunky (in a good way) and claustrophobic if the camera stopped when you reached the edge of the left screen.
