Baby Launcher got a little bit smarter today. No one has tried yet, but you could easily hack in made up scores and submit them to the leader board. In an effort to keep things fair, I beefed up the backend so cheating is quite a bit more difficult.
The Best score is your all-time highest score still, but the game now runs a session and you can submit your best score when you are finished playing without wiping your all-time best score. So, there is no need to spam the submit button, just play away and only submit your best game score when you are finished playing.
