This is really good! It's a shame you didn't have those extra 24 hours to work on it, feels like with a bit more content and a web app this could have been really popular. It's very polished, and although the concept is simple, it's a lot of fun, especially once you get to the later levels! Would love to see a more fleshed out version of this game. Seems like the start of a great roguelike, for example. Nice work!
