The MTTAF are walking on the boardwalk. Every few seconds, Minecraft TNT will appear randomly. It'll attack friends near the TNT explosion. If they died, they can respawn back in the project. You'll also see messages at the top of the screen saying if a friend died or respawned. You can also see all the messages and even lives by pressing space or by clicking/tapping the project screen. The messages list will automatically be cleared if you restart the project. The friends lives will be reset to 10 if you restart the project too. The TNT's explosion won't do damage to the background. It'll only do damage to the friends. If the messages list and lives are showing, the gray message boxes won't appear until you close them. If there are more than one message at a time, the gray message boxes could glitch and you might not see them all. Look at the messages list to see them all. The friends can regenerate health if they're not at full health (10). You'll know this by showing the lives.
