No, as the warning says on the download page, just extract the game into a separate folder and play
after a bit you can delete the old version
Noted and appreciated, though I feel the download disclaimer could be worded differently.
If I get my raise next week I'm putting the extra toward this. It's an amazing game, story, and characters you've built here, and it deserves recognition.
Thank you very much, I'll update the warning to hopefully make it better!
