Hi Silverfoxiee. Thank you very much for playing Eternal Winter! :D
Just replayed the game to make sure we hadn't miss something or uploaded the wrong version - both Aster and Leonis's route are complete and can be fully played in this version.
Do note that there's still a segment of the story missing during day 3, that might be what you ran into. If that's the case, worry not, we're working on closing that gap. Hopefully, it won't take too long.
