Perhaps you can create a WebGL build and upload the game to play.unity.com and share the link in Discord. Obviously, you won't be eligible for ratings, but you can still show your work! Just be sure to test the WebGL build!

Good work on participating in the jam, as stated below I was unable to play this. you need to zip up all the files and folders that are with the .exe file. I would be keen to check it out if you upload it after the voting has finished, and if you need some help uploading don't hesitate to ask :) 

Hey there!  I tried downloading and running your game but looks like it's missing some necessary files that Unity includes.  Got an error message that said "The code execution could not be completed because UnityPlayer.dll was not found."  Usually Unity includes all these files in a folder for the build, and then you upload the full build folder to itch.io.

Sorry it didn't work out for you.  If you're able to upload a build somewhere else, let me know and I'll try it out.
