I'm reminded of Spiritfarer with how the player character operates a vehicle while making stops at locations, picking up or dropping off passengers. Though it was hard for me to understand how the limitation was used, the concept, game design, writing, art, and music are all beautiful and cohesive - a testament not only to each member's individual capabilities but also to the team's synergy. Congrats on a great game - there is a lot of potential here for this to be fleshed out into something much bigger!
