Man, It is late...

I'm gonna go to sleep and then wake up and go to work. Along the way, I will probably pay the tolls at the tollbooths and flip through the semi-static of morning radio stations. When I get there I will mix some powdered creamer into whatever coffee is in the pot. What is powdered creamer made out of, anyway? But seriously, I have to sleep first. Just so you know.

hahah Nice

So I just read this book a few days ago, and then I was perusing the flash portal as usual and I was like "OMFG FLATLAND!! Is that THE Flatland???" and it was. A short little game thingie. Anyway I was like "There could be MORE!" and searched for flatland and came across your piece. Awesome! I love your ending. soooooo good. Hilarious.The animation is good and everything. Although one of those polygons was totally irregular. Probably evil. >POKE<

It was not as exciting as I hoped.

So, when you beat 40 levels and the sounds are off, the music still plays right when you win. Otherwise, cool game. Kinda generic. But cool.
I didn't feel like I "forgot what I knew about gravity"... I felt like there should have been some game mechanic added after each set of ten levels instead of just a "mode" that was unlocked. Like... "these blocks will start to dissolve when they touch each other" or "watch out! these blocks are ticking time bombs!" or "these blocks are attracted to each other"

AAAAAAAAAH!!!!!

This was absolutely terrifying. It scared my socks under my bed. AAAAAA!!!!!!! lol.

pressure and collision

So, the particles really don't interact with each other right--frequently liquid simulations are done with "cells" containing parker particles that are pushed outwards from cells with high pressure...and then you shouldn't end up with lots of particles getting stuck and just sitting there so you could get rid of the whole particle life thing, because particle life is lame.
Also, your collision detection does not check whether a particle is about to step through or through and past the white block, you just check whether the particle is inside the white block.
But you know, nice work. You should try drawing some curves around the particles so we can't see them. People would totally be more impressed.
