It appears your game has unexpectedly crashed, this can be because of various reasons:
1- You have downloaded a pirated copy of Duda's House in pages that aren't the Itch.io release, you can download it here
2- Your computer might not be able to completely run this game
3- You have found a mysterious entity inside the game (this one has been reported a lot recently and I'm unsure of what it means)
if you keep having trouble, get in contact with this email address dudasoft63@gmail.com (don't actually do it, this is all generic support page cr*p)
