I absolutely LOVE this idea! This could definitely be made into a much bigger game. The multitasking was just the right level of stressful and it made me wonder what it would be like having to deal with multiple games at once. One thing I would suggest is allowing the player to bind their own keys to each action when they are introduced, partially to make accessibility better and also because it would incentivize setting up memorable and easy to press keys for if you add a bunch more things to keep track of. Great job overall!
