Hey thanks for playing and for leaving us some feedback.
The infirmary will heal you up if you enter and head toward the center of the room, you aren't introduced to the med bay until later on in the story and that was a bit of a mistake on our end. We're looking into adding a tutorial or some tutorial events after the jam as well as increasing the pace of the game and improving the combat.
So be sure to check us out after the jam is over if you want to give a more polished/updated version a go.
