We'll have it back in the rotation in a week or two. This does mean that today's daily seed has been rerolled and today's daily leaderboards have been refreshed. Sorry about that! |

They also share 1-3 weird modifiers that make daily runs feel pretty different from normal runs! Dailies are scored! Compete with your friends on the Steam leaderboards! Daily runs are available after beating the game, OR by opting in early (and accepting that dailies may contain story/mechanic spoilers!) Here’s a few examples of daily modifiers: One character only! Enemy ship parts are randomly shuffled at the start of every fight! Start with extra health, but most fights take place in Solar Flare events- you’re gonna need the health Cards ca |
