Even at the rate stage, I marked for myself some of the participants with "post-ld" fixes. In some cases, these were separate links, but many simply left one link to the game. And this does not apply to fatal blockers, but ordinary improvements and bug fixes. And, as it turned out, such works in fact can take a prize. I certainly do not want to talk about the quality of the games themselves, these are amazing works with cool ideas and implementation. But isn't this a direct violation of the most important rule of jam - time limits?

Personally, I spent some of the time fixing bugs, which I could spend on adding new functionality to the game. So that later, after the jam, you can calmly fix all the bugs and correct the balance. This can go very far.

Is a simple "changelog" really an excuse in this case? Do you often see this? Can an ordinary participant do something about this?
