The mecanic is genius. I would require a better tutorialization, though, as I didn't undestand it at first, and had to read the game page. But it make interesting puzzle, is very original and fits the theme perfectly.
The art is great, one of the best looking among the games I rated. And the most complex by far. But it has readability issues, especialy the doors that are not visible enough. Also the chromatic aberation effect, while cool looking, hurts the readibility and is a bit headhache inducing after a while. Maybe tune it down.
