Hey this looks super awesome for your first project well done! BTW this jam does require at least 2 platform exports. In Unity when setting your export settings you have to select the platform in the dropdown (it’ll be Windows by default) and you can export for Mac or Linux to meet the rules for the jam. You’ve got plenty of time so just add that before the end of the submission period to be able to participate in the jam please!
I’m excited to try this game!
