Fridges are useful, and they can help people store foods such as vegetables, pork, beef, eggs etc, your mission is to dodge as many iceboxes as possible. When your score is under 2000, you just need to deal with fridges coming from the top. When your score is over 2000, refrigerators will come from both the top and the right. When your score is over 3000, freezers will come from the top, the right and the left. Good luck!
