So far a good demo.
I loved the animations, movement and combat style, that certainely gave me the momodora vibes. It's artstyle is simple and solid too.
I liked the limitation on the arrows to avoid camping, but eventually I ended up only using the knife, haha. I loved that you could aim the knife in such many directions though.
The music is a bit gloomy, and I think it last a bit long, which starts getting a bit boring after 10 minutes. perhaps you can spice up the moment you get your knife. A lot of Metroidvania's do start out with exciting music early, but that depends on how you view your game.
I do experience some performance issues in larger rooms, it might be my PC, but I didn't see why that could be an issue, but maybe this is something you could look into?
Anyways, it's a great game, you're making good progress and certainely got the attention.
I'm looking forward for it's release!
