Have you ever thought "I wonder what a plat-former would be like if you couldn't see the platforms?" You haven't ?! Well I did it anyways! In Sol the platforms are invisible (so increasing your brightness will do nothing), and the way to see is with a bunch of little light particles called lumen. In order to gain more lumen you can kill or befriend Lanterns that you can find as exploring.
