This is my first game post and my first jam. I uploaded incorrectly and my game is not playable for others. May I please upload the zip file?

I would say so, because this is all about learning and getting feedback, but I don't really know

Unfortunately, once the jam starts it is common to "lock" submissions or updates for the rating period. There are potentially ways around this though.

A similar issue happened to user Daniel with their game Robbo Redemption. 

What they did was upload a google drive link to their game, and made it accessible to the players.

What I would recommend doing is trying something similar or talking directly to the game jam  hosts, whose information is  linked on the main page   Brackeys Game Jam.

Best of luck, and I  hope that you are able to get your game working!

io! Let me know if you do a build for Mac, maybe you can post it here with the link to the rate page, I’ll love to try it!

good luck and keep on jamming in the free world.

Try my game.
