Sungrazer Mac/Linux Support!

Hola!

Finally, after way too much time, Sungrazer now has support for Mac and Linux! Along with Windows, you can now download Sungrazer on Mac and Linux from its itch.io page. I've also updated the install instructions so that you know how to play on each one of those different devices. Also, I've made a color palette for Sungrazer's webpage using coolors.co, because I think everything would look better if it had a good color palette. I'd also recommend the same for you if you're making a video game, itch.io webpage, or just art in general. TL;DR: Sungrazer is now playable on Mac and Linux and there's a dedicated color palette for its itch.io page.
