We've done a number of updates over the last few days, here are the combined patch notes for these changes:
Our main focus for these changes has been to make the game more friendly to beginners. We've selected out a few levels that are easier to get started with, which the game will now recommend the first time you start a lobby.
We've also introduced an option to change how much damage you take from leaving the edge of the screen, which allows you to bounce back one or more times instead of the previous instant elimination.

This will now default to 50%, which means you will survive falling out of the map once, but if you do it again before recovering your health you will be eliminated. We found this option makes the game much more focused on playing to defeat your enemies, rather than waiting for them to make a mistake. You can always change this option back to 100% however to go back to how the game was before.
With these changes, we've also made some tweaks to decrease how fast you recover from a knockout and the health regeneration rate, to give players more time to throw out their opponents from the map after knocking them out or damaging them enough,
