Due to the nature of game jams, it's difficult to find the time to properly playtest the game, and as such game jam entries are often somewhat buggy. I have identified several bugs in my game and fixed a lot of them, and am now sitting on a hotfix for it.

The reason I haven't immidiately released it is that I'm not sure if updating the game is allowed in this time period. I think it's reasonable to assume that updates that introduce new content or features should be put off until the game jam voting closes so as to not affect the scoring - it would effectively allow people to work for a few extra days before everyone gets around to voting. I also think it's reasonable to allow a hotfix that doesn't introduce anything new to the game, but I figured I'd ask first to ensure that this is in compliance with the game jam rules.

Is it okay to release updates to the game jam entries?

I would also like to know this answer as some of the sounds in my game are way too quiet when sound is the most important part of the game.

Yeah updating it from now onwards should be disabled. But then again it shouldnt affect our ratings too much as the gamejam is small.

after you publish your game there is no way anybody can determine if you updated your game. And if your game is webgl, nobody can tell the difference. I think that bugfixing and post release content is ok. Goal was to create game in some short period. Finishing core game and publishing it before deadline is goal. Tell me one reason why i couldnt fix bug which somebody found after release. It happened to me, i fix it. And its ok
