Well done. What a charming game with just a one-button interface. Absolutely gorgeous and a lot of fun. As you know, I am not a "good player", so I would wish
1. A much bigger hitbox on the apple. It is frustrating and annoying that you fly through the apple and see "nah, not quite, sooorry". I understand that a bigger hitbox would kill the challenge, so: make the apple at least thinner, so you do not fly right through it and it does not count. I still made all 20 levels, though ;-)
2. Slightly slower swing and/or some slo-mo turn. If it would take another button/key, that's probably not what you want, so what about: Slower swing when you connect a new candle and the swing (rotation) speeds up the longer you are connected!?
I would also like more different candles. Eg:
- Different swing speeds
- Candles that attract even without connecting would be nice
- Maybe "Dark Candles" that pushes the moth away
Whatever: Well done, really cool game! Make it "full" :-)
