I don't believe that complicating the controls should be the challenge of a game. I understand the original control, but crashing into the edges and not being able to pick up the food, I don't consider that a good challenge.
I liked the graphic atmosphere, but there is a rather unpleasant sound that sounds like a toilet.
The effort to create such an original control is appreciated. It's a shame about the gameplay.
It is indeed a loop, but I don't think you're trapped in it because you're creating other loops.
