I am a DEV of games with Construct 3 and I am using this plug-in that seems wonderful to me, also if the author gives excellent support for his community on Discord. With this you can have your table of records of your players running on any platform, be it HTML5 or native Android or iOS in a simple way with a Firebase database, if you want to have this in your games, do not hesitate to invest in this plug-in.
Thanks to this, my next games to come out this year are with your online high score table. Thanks Sparsha !!!
