Just going to give this a little bump. 4 days left if you are going to get an entry in so don’t forget the deadline!
If still thinking of writing one, given it’s only <500 words (excluding code) its very do-able if you have some time over the next couple of days, and it’s a low pressure game jam for a good cause. And its a good challenge to keep to a short story and try only have a few interactions which count to keep the word count down. CSIDE will count prose only for you so you don’t have to do a hand count with is great too 
If anyone has any problems getting CSG’s to host properly on itch, happy to help. Here’s a rough guide to the settings you need. If you have any images in the game, you’ll need to put them in a folder with the compiled game (name it index) and zip it for upload, otherwise if no images, just upload the compiled file.
