I absolutely loved this game. Didn't however manage to do the 3rd level as I couldn't find out how to flip the switches in order to open that door. Also couldn't find the key for the 3rd door, on the left. Graphics were very familiar as I love that tileset and I think you did a great job playing with the deminishing light. Would love to try again, but could probably do with a hint in level 3.
Will post the timestamp from the stream later.
