I didn't understood the game at first, I had to read the game page to understand it.
I managed to finish the game but it was a bit frustrating/long as when I lost I didn't know why I (because otherwise I wouldn't have lost). Some of the anomalies were a bit too subtle.
The clock counter was a good idea, fitting both the gameplay and lore.
Great ambiance, nice endgame cutscene. Graphics could have been a bit more polished as there is only one scene (glitchy shadows etc.), but overall it looked ok.
