v0.2.0 Release - Updated Leaderboard

Hi folks! 

After #KenneyJam24 ended (congrats to the winners!) we wanted to clean up a few things in this jam release. 

While the leaderboard worked, one thing I didn't like about this implementation was that it only stored a user's score and initials to the leaderboard API if that user made it into the top 10. 

With this update, we've simplified entry of initials into the leaderboard and added some text validation (3 characters required). Now, if you play once, you can enter your initials even if you don't make the top 10, and the next time you play from the same machine, in most cases you shouldn't have to enter your initials again. 

We may add another small update to the gameplay before fully wrapping up this small project, but we're already very grateful for those that took time to play our entry and for the kind words about it.

If you liked the leaderboard implementation and would like to make one like this yourself, I'm also putting together a blog post and demo project to show how it was made. Look out for that on https://blog.artemoosegames.com.

Let us know if you play the updated version and encounter any issues.

Thanks for playing!
