Nice idea. I started running back to the shops after my knight got to fighting. But after that I got back I couldn't find any more enemies. I flagged my knight for many screens but after the first few there was just nothing.
I think it's better if you could switch modes without pressing escape. I also couldn't detect a progress bar for cooking for sharpening swords. Having visual representations of the squire's state (and preferably progress) would make the game much more readable.
Fyi, 'source' is a field where you can indicate where the game's source code can be found (in case you open sourced it).
