Glad to hear you're enjoying it!
There is actually no repair hammer, the game is beatable by only fighting a few things and shooting the bow maybe 20 times max. Combat is meant to be avoided, but if you find that you break your bows and are unable to make enough to complete the game - let me know and I'll make a change.
There are no traders at all in the game, you're the only living guy in the area.
