Unfortunately the game does not work :/
After the loading bar, part of an oversized image is displayed. But you can't get away from it.
If you're still interest in trying the game, this alternate version should work: https://dylanbb.itch.io/christmas-with-gus-gus-window-size-fix
Thank you for your comment. I think I know the source of the problem... I added a line of code to make the game look sharp on Apple's 2x Retina Display devices, but it seems like it's not working on non-Apple devices and causing the entire game to be 2x in size. Unfortunately it's too late for this game jam but I'll fix it for a future release! If you want to try the game for now I think you have to use a Mac or iPad.
