This was a pretty solid entry, especially considering that it’s your first game jam! What a way to start!
The game was fun, short, and sweet. Really liked some of the mechanics that you had. It took me a while to know how to repair the machine, though (Mostly because I couldn’t find where the missing part was), but once I did it, everything went smoothly.
You could improve the way texts are being shown as well. As of now, they’re a little bit slow, and you can’t seem to skip the animations, as another comment mentioned, so that can be a little furstrating.
But overall, really nice job!
