Hands down my favorite game of both this jam and all prior jams. The digging mechanic is gloriously smooth. Love the humor (do more of that). As others said, you can easily flesh this out into a demo for a full game. Make the cure for mom more expensive, add more upgrades like more space. Add more random audio things. Another layer below to dig to create more machines. You have the foundation of a stellar hit here that could catch on with streamers.
