I did a quick run on the web version. I was able to sneak attack everything on the first two levels, which felt like a bug, but I'm honestly not sure.

When I found a spear, I kind of expected to be able to throw it, but I didn't find a throw option anywhere. I think that makes the short sword better in every case, but maybe I missed something.

Overall, I love the execution. Quality retro fun with a really nice interface.
