I've added rare gem rewards per mini-game levels, you should be able to check progress on all games you're playing. The plan is to set up a shop with in app perks (maybe glowing username, custom badges, etc) and you can use the rare gems to purchase them. More soon..

you can now buy small (visual) profile enhancements like username highlights or gradient background, etc using rare gems

That sounds cool! Also, where do you see how many rare gems you have, and how do you get those extra things with them exactly?

on game pages you have the level progress bar and on the right side there's an arrow you can tap that will take you to the gem shop. you can see your gem balance and the things you can buy with them

Ok ty 👍
