Very well designed game! Everything is polished and fits together.
The only critic I have to agree the previous comments, it is really hard and gets even harder after the first time your candles run out because of the lack of spare candles.
But i like the idea of hiding the color changer in the settings, this is in it self another puzzle, to find out how to change the color. But with the already hard time limit of the candles it doesnt really work out. Burned through like 3 candles to try different colors and couldnt find everything in this room.
