This is a fantastic proof of concept for an involved strategy game that pairs a little of Oregon Trail with network-building. I was sincerely really impressed by this. It has great potential! Some of the highlights I really liked were the narrative focus, with encounters and quests thoughtfully played out in dialogue and user choices, and the gorgeous minimalist pixel art, which reminds me a little of those big Ultima map tilesets from back in the day.
The core gameplay loop feels good and the events aren't so common as to be obtrusive. Dragging and plotting out roads and travel destinations feels pretty intuitive and easy too! Currently there are only tradeoffs in terms of affecting fuel and resources, which aren't too much of an inconvenience. I can see the game taking on interesting dimensions of trade or exchange where the resource management becomes more involved over time and factors in more of a challenge.
As far as constructive feedback, there isn't a lot - this is super polished for a jam prototype and all its systems work well. The only thing I can think of is that I was surprised roads offer no real bonuses to the player once established - travel is the same speed/cost (?) and the autosuggestions for travel routes don't follow them as a result. I wonder if there were more benefits constructing roads and even other things in future could provide for the strategy element?
Congrats on publishing this - I really enjoyed playing it. I would love to see how this evolves and try it again down the track, and really hope you continue development on the prototype!
