Just wanted to share some things I noticed while playing the game:

1000pts - Lamp Post appears
2000 - Tree / Red Boxes
3000 - House
5000 - Sunset / Blinking Boxes
6000 - Lamp Post Turns on
8000 - More Trees
9000 - Even More Trees
10,000 - Gets Dark, Moon appears
11,000 - House lights come on
13,000 - Lights on tree

Once you reach 18,000...the boxes fall even faster and it's easier to get multiple box bonuses, which will boost your score rater quickly, but it's easier to get hit as well.

Also noitced the bonus points for hittin multiple boxes with one shot:

2 = 200pts
3 = 800pts
4 = 2000pts
5 = 3,200pts

I havn't hit more than 5..so I don't know any others.....

Feel free to add anything that I may have wrong or have missed.  =)

Awwww Nicky! Thx for the tips!!

Nice observation.....yea the boxes fall a lot more faster than before when we reach around 15000 nd above..

it's 3,200pts for 4 boxes
i never hit 5 but i think the bonus would b 12,800
cause each box multiplies the bonus by 4
