Not bad. I honestly think it would have been better without the "romance" side plots as horror and romance usually aren't genres that work all that well mashed together unless you're reaaally careful about it. Besides that I saw a few issues with the whole concept, mainly because spores are like, really, really tiny, like way tinier than you probably realize and unless the characters are in a truly air-tight hermetically sealed enviroment that entire city would have been wiped out already, just keeping the doors and windows closed really isn't going to be enough to stop spores from getting in. Finally it's the ending kind leaves the player with blueballs, but I imagine it was probably a quick solution to meet the jam deadline, so I don't hold it against it too much, but overall it was a pretty fun story and I'd be interested in checking out some of your other work.
