Thanks for the feedback! These are great ideas.
What you're describing for how the game works is entirely by design and intentional. I didn't want it to be stressful, or even very hard. Its designed to be something you can pop in to whenever you like and have some fun with it for however long you want.
That said, I do have some ideas for some variations on it for folks like yourself that want more of a challenge - so maybe a sequel for 2023!
