Very short but polished experience. I have to admit it took me an embarassing amount of time to figure out there were two doors and then which door I was supposed to go through, but once I figured it out it was all good.
It was a good instinct to make the anomalies quite obvious, afterall this is a game jam and you are fighting against a limited attention span per player, however I found myself wondering if the anomalies could be slightly subtler while still remaining readable.
Technically speaking the sounds were well balanced, the presentation stellar and I had no frame drops even in the browser - impressive.
