Woah, this game is like a tiny FPS where you're a doctor shooting germs with medicine - super chill for a quick play. If you're into games like that, check out https://monopoly-live-casino.com/. I’m all about their Monopoly Live game - it's got that live dealer vibe and some cool interactive elements.

Everything you have described in your document seems simple and doable. My only concern is that it seems like kind of a "one and done" minigame similar to what is seen in microgame collections like the WarioWare games. If that's what you're going for then that is perfectly fine. My only suggestion would be to possibly try to find some additional way to vary up the gameplay experience from level to level.
