Haha, fun concept! And can I just say, the main menu design is really neat. It does exactly what it needs to do: start, exit, volume. But as someone who's studied a LOT of main menus to learn how to do the design really well, I feel this one sits really high at the top of the list for me. Really cool vibes.
The polish on this game is really high for a game jam. I'm really impressed with how robust the game mechanics are. If you decide to continue it (and you should!), it would pay off immensely to pour some time into playtesting and tutorialisation. Not necessary a "tutorial screen", but a way to implicitly tell the player how to play your game. Check DRC, for example. I seeded throughout hints on what buttons to press, only at the times it mattered.
Accessibility is one of those things that is really hard to remember to do, unless you're constantly playtesting with strangers. And then it's immediately obvious if it's lacking.
