Hi, I played your game, and have the following comments :) Thank you so much for sharing!
Things that I liked:
* The many different characters and had different styles.
* The upgrade system, where picking up souls would allow me to become better.
* Progression system was fun and clear.
Things that I would improve
* The feedback in the game seems weak, I am not always sure what is happening, and it feels mechanical and rigid at times.
* There is no clear goal, or anything to do in the game that keeps me motivated, surviving for 30 minutes, does not feel like enough.
* Animations for jump and dash needs some work to feel better.
All in all, this has potential, and I am looking forward to more updates on the game.
