[IMPORTANT] For those with integrated graphics cards...

The WebGL AttachShader error that some players are reporting is a problem that can occur with computers using integrated graphics. However, there is a workaround.

Step 1

Right-click on the game in your Steam Library, and select properties.

Step 2

Select the Betas tab, and choose "integratedgraphicsmode"

Step 3

Allow the game to install the IG version, and you've done it! Please note that features such as achievements will not function in integrated graphics mode.
