So first of all, I almost gave up, but I always read all comments and information after I complete the game. I could not figure out the candle lighting system. After reading I finally figured out you have to pick them up(I finally saw the prompt to pick up, I'm not sure why it never showed on my first playthrough). In my opinion, the candles should start in your hands and then you can choose to drop it to grab another.
Anyways, after playing it through I DID enjoy it and liked the decision to only take certain candles that can only see their color's platform. As others have said I didn't enjoy the controls with switching and lighting candles while also trying to platform. Good game and concept and keep on creating at the young age, you are doing more than most with others your age.
