Hello! This has happened to other user too previously and I have no idea what it is.
Please check again, I just reuploaded the file.
Thanks for the feedback! I really appreciate it. The reason the sprites have a 2-frames walk cycle is because the sprites were originally inspired by the NES Castlevania games, but I will definitely consider making them 4-frames now that you mention it.
As for matching the fidelity of Astalon/Alwa's Awakening, I can give it a try. Feel free to contact me on Bluesky (in my profile) or Discord (username: elsrech7702112)
