For people who have linked their account to google play and still want to use the mod. You can link the account again on an email by going to the sub menu (4 squares on the upper right) clicking account then going to link account then click on the link email account option. This will bring up a screen where you can make a password and the game will send a verification code to the email that you used. Once this is all done you can go back to the login screen and loging via the email and password that you just made. Hopefully this helps you guys. Don't use the mods on sections of the game that will show up on the leaderboard and make sure to clear stages at a reasonable time example 30 seconds for 1 minute and 30 second stages, 1 minute for 3 minute stages etc. In coop just use defense mod or 1x damage.
