As a small indie development company, Neverworks Games is always looking for ways to keep development costs low. There is a constant need to come up with icons, but I don’t want to use common libraries like Font Awesome too much. I don’t want my games to look like a web page! But I did find an awesome website called Icons8 that has a plethora of free icons. I used them quite a bit in the development of Firmament Wars for its in-game iconography and for its Steam achievements.
Where needed I also made minor adjustments to some of the icons such as changing the color to grayscale or rotating their hue, but most of them were used as-is!
