Is my game submitted or just a empty page ::(
In your game Grid of Madness, you have a download button for a rar. Does the rar contain an executable? Than I think it's ok. In the settings of your game's page you can mark for which platform the executable is (Windows, Linux, etc.). If you want to make your game playable in the browser, you need to upload a zip folder that contains a working web build as well as an index.html which is the entry point for your game.
Edit: just saw that the rar contains a Unity build for Windows, this should be totally fine. Just label it regarding the target platform. Also a tip: in Game Jams it's often better to aim for web builds. A lot of participants don't want to download anything, even if a build for their platform is available.
I downloaded and tested it: it opens fine. Tianmaru is right, it is better to aim for web games. Many people are using itch.io from a browser and not the client, and don't want to download the file and unzip it manually. But if you do, I would also recommend having a folder that contains all the build in the zip file, so that people won't need to create a new folder for the game on their own, so that they can just drag and drop the pre-created folder with the game on their computer.
I played around for a bit, I like the idea, but I don't understand how to cooperate with the robot? It seems like it moves randomly?
