Thank you.
I'm glad you have enjoyed the art and style so far it was wonderful to have this jam to work outside the box and to draw everything i needed, it was a very enjoyable experience.
About the proof of concept, well, as you saw already there are some features still not working, like the cargo on the UI.
Game also need a lot of work on the economic aspects and some extra railroad related buildings to interact with.
Of course the game needs a small tutorial when all these features are implemented, I am already planning how to do that and have a small route between the newbie towns for the player to get used to the mechanics, that still will be simple, but i hope still enjoyable.
Thank you for this jam idea, it's wonderful to see there are other people experimenting with this engine trying to get out of the box, also this experience gave me some ideas for another kind of game using the same engine and theme.
