Well, unfortunately the game will not be able to upload to Gamejolt or play it using Gamejolt as it cannot transform SB3 files to executable. I will put to download the SB3 file of the game to which they should have Scratch Desktop for this to be possible (you need a somewhat powerful pc so that it does not crash) the other option is in the official page of https://scratch.mit.edu/ but it may be somewhat lag as the game is too heavy for the page, the game will be available on the page in an hour or minutes. Look out for my scratch website.

I wish you a merry Christmas!
