Can you make a version that can be downloaded to Android (as well as Windows, etcetera) so it can be played offline?
Internet isn't always available on my phone. As for why Windows, we have poor connectivity out in the country, which when compounded with a storm can leave us without internet for hours to days.
If it's not something you're able or willing to do, don't stress over it. I, and I'm sure anyone interested, will still play it.
