I got stuck on the ceiling in the first secret room in the level after the dark level and had to restart the game. I would put a yellow pad in there so people can get down. The birds are a nice touch. The amount of branching paths is impressive. I do wish my best time was displayed on the title screen. I was not paying attention to the timer so I don't know how long I took. I know my time was bad. I spent a while exploring every nook and cranny of the new levels.
