Neat little game, really liked the artwork for the character especially! Could quite figure out what I was doing wrong in level 3, but overall I definitely like your interpretation of the theme.

The way how level 3 works is: When you open or close doors, the smell of the pudding will start to slowly "linger into" the room, or slowly "linger out" of the room. To solve the puzzle, you need to take advantage of how slow it is for the smell to catch up to you.
Basically, you need to flip the gray switch, then the blue switch, after that hit the gray switch again and immediately run to the left and fall down.
I see! What seems to have been happening was that you must be incrementing the value for the smell creeping in every frame, and since it was running at 144Hz it was happening too fast for me to make it through. Once I changed my display to 60Hz, it worked as you described.
Timing can be tricky! For this kind of thing you'd want to either increment the values on a physics timestep (if Godot has something like Unity's "FixedUpdate" function), or save the time when the transition started and compare the current time to that (divide by length of transition and cap the value at 1 to get a 0-to-1 value). Hope that helps a bit, keep up the good work!
