Update: Yes, It happened with me today, white screen, that was weird. I think it happens if you have RPG maker MZ (or another version of it) running in the background, it will give you this white screen. Please close your RPG Maker software and try again(let me know).
No, you don’t need to do anything—just run it. It might take 5-10 seconds to open because of the compression, but it runs smoothly after that. I’ve repackaged it slightly differently this time, so if you want to download it again and give it another try, I hope it works now.
As for the game not showing up, yes, I noticed it doesn’t show up in the search results. I assumed it was just a delay on Itch’s end and that it would appear after a few days(I will email them regarding this). Regarding the name itself, I’m considering changing the world name since I’ve realized it’s already being used by some other games.
