Great entry to the Metroidvania jam! I love all the different perspectives that you wrote this game from. The gameplay in general was quite good, if a bit repetitive. Level design was a bit repetitive as well, but you made a pretty huge map in a month so not a big deal. I really don't see how you did all of this in a month. I may have missed it, but an option to turn all of the blood off would be very nice; I wouldn't feel comfortable playing this one around any sort of younger kids.
I love how you can chain attacks together, and the enemies can as well! I have quite a few different feedbacks for different aspects of the game; let me know and I can leave them in a comment here or send them directly to you on Discord, email, etc.
