In the rules section they say "Game files are not locked so if you discover a major issue with your game file it is possible to change this afterwards, just make sure you make a submission before the deadline. " what exactly counts as a major issue? 

Here are some of the issues I have, but I don't want to get disqualified if it's not a major issue

1. My games level changer collision box is in the wrong position so no one knows how to make it to the final level

2. There are controls for arrow keys but the action keys are still shift and space instead of z, x and c, making arrow keys virtually unplayable

3. The games resolution is 1920 x 1080 which makes it a little bit to big for the itch page and I cant resize it in the itch because it anchors to the bottom left

Ok noted thnx for the response

You can write to the organisers in discord, but I am 99% sure they will tell you that those are not qualifying as game breaking. As long as people can play it, and even finish it, it is what it is now, unfortunately.
