the best way to beat a lv. is by putting the mouse lv. to max and then go up to the enemy base and keep calling the mouses ( make sure to have the aura thing) then when the aura thing becomes in sight of the mouses the mouses will jump and attack causing heavy damage ( also keep pressing 1 so u can repeatedly call the mouses. ur welcome.
