Flatline v1.3 with Live Highscores!

This is the final update now. For real!

Changes

• Live online Highscore Table! Time to begin the score chase! Don't try to cheat with autocomplete feature as it would not be registered as a highscore.
• Change your name in the game. Note, if you want your highscore to use your current name you must change it before starting the run. Changing the name post-run would only change it locally for you. 
• Few minor fixes here and there

Now we're going to move on to the successor project!
