Use the numpad key 5 to position the point to the center.

As stated, DDS isn't supported.

The two textures will likely use the same VRAM, as the 500x500 will occupy a 512x512 texture.

Compare the layer the sprite's on, don't use a private variable; considering using families.

However, the error is because your image is not power of two, as it says. It should work with 128x128.

DDS won't work with the current version of Construct.

The text manipulator object provides an easy way to replace things in strings (though it can be done via system expression also).

Really? A lot of shaders replace pixels or modify their position.

How would the runtime know the effect isn't going to flip a sprite which is half off screen? It has to process the whole image.

The installer removes any old registry settings. What more do you want to remove? There's a .ini file in your application settings if you want to go the whole way, I guess.

Why not install it normally?
