Thanks for playing! I used a free service called Loot Locker for the Leaderboards (I still had to set up the UI and game logic separately). I really appreciate all of your feedback.
Thank you, i will look at it :) As i understood for small scale games it's basically free? Do you have to add credit card for free plan?
It's completely free for up to 1000 users per month. I don't recall needing a credit card to sign up.
Nice, thank you for info!
