Thank you! Music making is already my long-term hobby so it was the easies part to finish :) BTW let me know whenever you need any help with music and sound design - we could collaborate someday. Considering the health representation, yes I already thought exactly about border density or tinting or maybe adding two pixel orbitals/pets or smth :) There are already particles implemented and they grow in size when you collect more and more bottles, but it is not very good solution because it works more like a decoration than some informative element. I hope that I will implement a more appropriate solution this Friday.
