The most surefire way to update the game is to delete the entire old PvZ_Travel folder and install the new update (on PC, this won't delete your progress). The game won't automatically check for updates. If you want to get the latest update, please come here and CHECK THE DEVLOGS to see whether it is updated.

For online versions, please clear your cache and cookies to apply the new update to the game. Instructions for clearing cache and cookies can be viewed here. Clearing your web browsing history is also recommended to smoothen your game experience.

Performance tips:

<PC> The smaller the game window is the smoother the game will run.

<Android> Playing the game on the app will ensure a smoother experience than on browser ("Play Online").

<iOS> It's still playable, but not fully supported by iOS devices (iPhone, iPad), more specifically the visuals will be a bit messed up. There's no app version for iOS so your only choice is on browser ("Play Online").
