I put it that I credited where I got my art ingame but I only put it in the resources folder. I fixed my itch page so it says where I got my art but does it matter if I put in something wrong by mistake or do I have to resubmit my project with the correct response?

You should have an “Edit Submission” button on your jam entry page. You can get there by clicking “Submission to VimJam 4” at the top right of your game page, then click “Edit Submission” to update your responses.
