Yeah I did! I got 3rd place earlier, almost took 2nd place. That 1st place is pretty scary though hahaha... Now that I think about it, it looks like there's also a working server-side leaderboard implemented here, damn that's even more impressive.
Wow so close to 2nd - that must've been frustrating! My friend hit first place yesterday (he was aiming for 1 mil points) and I get the feeling no one else is gonna get close lol
About the leaderboard, it was actually insanely easy to set up given how much it adds to the game - in case you're interested in giving it a shot I'll drop the vid I followed. It only took me like 20 mins to get the functionality down, and I've been able to reuse the code super easily!
