Simple 2D Shader Test

An old test application for 2D GLSL shaders.

Very simple app made in GameMaker Studio 1 showcasing some basic 2D shaders written in GLSL from when I was first learning shaders in high school.

Controls

Right Arrow and Left Arrow to change shader.

Mouse position to manipulate Fish Eye and Outer Blur shaders.
