This is in the wrong section by the way, should be in "Tech Support".
What's going on is your graphics card, or integrated graphics, does not have GLSL or OpenGL2, which is required to play Mythruna.
Some ways to fix this:
- Make sure your drivers are up to date.
- If you're on a laptop, it might have two graphics cards, integrated and dedicated. Make sure it's using the dedicated.
- If you're on a desktop, you might need to replace, or overall get, a graphics card.
Sorry, as this is unfortunate.
They grow up so fast. Good advise Shzylo.
