In the red area (bottom left after killing the big bat) I somehow glitched my way to the area where you get the double jump cloud. I couldn't repeat this though. I went down to the room with the save point and immediately went to the top left door without saving. I spammed jump while going through the door and it took me to the double jump room. I died though. Then I went right from the room with the save point in the red area and got shot by a skeleton. This made my character invisible and clicks stopped registering. I somehow kept moving through rooms though until I got to a room with no enemies and a flying money bag and the only command was jump, but the game wouldn't progress any further. Fun game, but really buggy.
