i LOVE this concept,
EpicToastTM basically said everything already, but a couple more points couple. something that threw me out of the experience was the UI wasnt pixelated, as well as the text above the travelers.
edit: the text and ui IS pixelated however the font looks default which throws the vibe a bit.
there was no real tutorial.
and it wasnt snapped to a pixel grid,
that last one is a personal preference thing,
a couple suggestions for the gameplay loop, maybe beside each quest have a failure success rate, based on the level of the traveler you are giving the quest to, i was kind of left blindly guessing which travelers could do which quests,
have some reward for successfully finishing quests, maybe be able to sell the items you get from quests,
Maybe make it harder to fulfill peoples requets, reiterating what epictoast said, i was able to easily complete every persons needs, so i ended up just spamming how can i help you
but all of these are just minor tweaks, if this will continue development. a little balancing and a reevaluation of the core gameplay loop, would truly make this an awesome game
PS: sorry for the long post, i just really think this game has potential and would love to see it continue development
