There's a chest in the house with a tool (all tools are random) in case you missed it, and you can stay at the inn (A on bed) to fully heal as often as you'd like! There are also a few healing items you can find if you explore in and near town really well!
I made it by spending far too much of every day working on it, but I've been prototyping similar games for a while so had a good idea how to go about it!
