I love the challenge and this easily can be expanded upon, like creating a way to remove zombies, different levels, making so that you can use some of the medical items for defending yourself from zombies, obstacles that only a player can get over, like a door which you can shut and it buys time for you to do smth, adding wounding system. Great idea with some polish you can make this into something commercial ;)

Thanks for the compliments and feedback!
We actually shared some of the same ideas during development (using medical items to slow down zombies, making this a level-based game where saving 5 patients would advance you to the next level). But due to time-constraints, we ended up just focusing on delivering a minimum viable product.
Sounds like we're on the same wavelength!
