very nice portal effects maybe their can be a shortcut that allows portals to give off warp kind of like there is a vine toggle button. this would be a cool little sci-fi feature that may add some complexity to portal1
I have a bug coz when I save something for example a bomb and I open it put it in the same place the window closes :( its annoying. And also as I open powder toy the are two windows one is official powder toy and the other is just black and as I close the black one the powder toy closes too. If you could Simon get rid of that black window that would be nice :) P.S. I love the portal and the categories and also the wind is quite cool too. by the way good job ;)
@marek11 @Vovix Could you both please take a picture of the blue screen or record the text that is displayed, this will help us find out if it's an issue with The Powder Toy or just your computer.
