My first reaction when I found the game:
Wow, look at all the pwetty thingies :U
My friends' reaction when I showed them the game:
Dude wtf Call uf Doody haz bettur graphicz then dis.
or...
WTF this is just a cheap copy of Dan Ball.
And then I decided to get new friends..
My very very first experience with powdertoy was when I was on the computer with a friend, and he wanted to show me it. Problem was, the school monitor's resolution was horrible, and we couldn't click the close button.
I slowly filled up blocks of walls with OIL and ignited them with a bit of LAVA to make a flamethrower. I then added URAN to try and make a nuke.
Oh look what I've just found, 2010 stamps.
(A screenshot from the latest tpt, as the old one doesn't show the stamps).
I used to make really crappy saves which I stored as stamps, fortunately I didn't upload those. These are probably not my oldest ones though, I remember some saves from an even earlier version.
