I played until the end and thought it was pretty fun. One thing though is that enemies can stack and that means you can just herd them into one giant pile. This paired with the fact that there is no cooldown to the sword that I can see, makes it a bit easy. If you make them be able to walk into each other and also increased/added a sword cooldown, it would be pretty much good. Also the path is a bit hard to find, but that's fine.
