Yep, just download the newest version available from here! If you got DLCs, you need to copy the files into the new version as well
The art is beautiful, and I love the darker/mature themes used in this. Along with that, I love the aftercare screen as the first ending I got was a lot to process. All in all, a wonderful game and I can't wait to see more!
I basically just binged all of the game's contents in 2-3 hours, but it's so good! I'm so excited to see what comes next for it!
