I now have an idea of how to approach my IGMC entry for this year's theme, as well as a working title (TBA). Given the limited time I can spare, I'm going with a game design that doesn't require a battle system. Something that could be expanded if I want to make it a longer game, but can probably be played through within 2 hours (the goal for now), at least on a speed run.
But you're right, If you are or know an elder who needs aid getting around, it should be taken quite seriously!
