I know that feeling! For me, one of the appeals of game jams is that they offer a "safe space" where a little project can be worked on without spilling over and gobbling up time that I should be spending on other things. It's still very hard to let go, though (some of my jam games have turned into larger projects ^_^)!

The Linux build ran fine, although with the binary uploaded the way it is, I had to manually give it "executable permissions" after downloading. Most Linux users know how to do that (typically, it's just a matter of right clicking on a file in a file browser, going to properties, and clicking a checkbox). It's not a big deal, but if that's something you'd like to address for future projects, I'd be happy to share some advice.
