Your game take inspiration from hollow knight, blasphemous and I suppose bloodborne for his aesthetics. It is good pixel art, even thought there isn't much finished asset I can see the work on the drawings.
Now the game also introduce combat and platforming:
- I don't know why I get so bad performances of this game, let's say I play on a old pc and optimization is not a priority for a game jam, I understand
- I really need my imagination to see how combat could feel good, but in this build the hitbox of my sword appear first frame when I hit the button, so it don't match the animation. Also enemies don't really have indication for their pattern, resulting in weird combat when no sprites touch each others with their weapon but still damage themselves.
- punishing platforming with barely visible mushroom hidden everywhere.
All of the above can be fixed, it's not inherently there because of design flaws.
Except for the dash and your healing system that feels complete and working, I felt you wanted to put too much into the game, resulting in a lot of barely functional mechanics scrapped together.
Still, I like your art, your ideas, there is potential there
