I tried clay.io in my game, though I run into problems especially on mobile. first one time safari crashed when login windows showed up, other times, I had hard time entering in my guest name, or closing the window. it seems a hassle. I ll check more on clay.io if there are solutions using their api
but is there another better alternative we can use with construct 2? if publishable with game on scirra site that's preferred but not necessary. a good leaderboard and achievement . would be good if I can integrate their login into my game without some heavy window. for example people who want to play as guest.
or is it better to code my own? what have you tried for your own games?
