Thanks maniac and @TristinAubin, I draw everything pixel by pixel, so when you get close there are more pixels to draw and hence the lag. I am hoping to improve it in later updates.

I do not believe I stole your idea. I did this based on your suggestion of a 3d engine. I thought you were suggesting I do it, not telling me you were doing it. Am I confused on something here?

@Erdelf, in reply to your earlier comment, that is because it draws individual points on the screen to represent the texture, and when you get really close, it does not draw enough pixels to look completely flat.

Try to move the camera so that the 'Login' cube is halfway outside the screen. but WOW, I'd really like to see this when it's finished! it is so cool!
