Extreme Burger Defense — Strategy and tips

• Unless you're about to lose, prioritize collecting money over spending it. You can always spend money later, but you can't collect money later, because it disappears after a short time.
  I'm not saying you should save money, definitely not. But spend most of your time collecting money. When you do spend money, do so as quickly as possible, and when there are fewer coins laying on the ground.
• I very rarely upgrade. (see above; it takes too long to click the upgrade button)
• Major spoiler: Bears only travel to the top edge, never to the left / right / bottom edges. (hilight with your mouse to see)
  This could be considered a bug. But it was probably marked as WONTFIX due to the extremely limited development time, and because it's possible to construe it as a game mechanic that the player has to learn. (though a surprising mechanic)

Game rules
