After your release to STEAM, the community has been asking and many are on the board of buying it, but some sort of multiplayer *any* would make them purchase it if it means they can play with friends and relatives.
If you are new to networking or hate it, I do not blame you, but the feature would be a simple yet big leap for the game for sales and play ability.
I hope this is not a repost from someone else, but even if it is, I hope some sort of simple multiplayer would be added at some point.
Cheers!
