Obviously this is still in development, and I feel like there's not enough here to really evaluate the game you're trying to make--you have this intriguing-sounding backstory in the description, but what we see in the game is a princess fighting slimes, and I'm not able to really gauge how they will connect. (It's also got quite a few bugs.) It's an interesting idea though, so I'd be interested in seeing it when it's more fleshed out.
