This is is SICK! Awesome job. Your music reminded me to Rory Bjorkman's Sci-Fi Fantasy armor knight artwork, check it out https://www.instagram.com/p/B_Qc5mJDS6D/?utm_source=ig_web_button_share_sheet (Idk why the link doesn't work if you click on it, plz copy and paste it)
I love the dark and glitchy sounds of the synths, a lot of feedback and flanger like sounds. It's a very unique soundtrack specially for this type of game. I would love to see this is a full developed game.
I'm not very experienced in Electronic music, so I can't give you any useful feedback other than you rock! The magician's theme gave me glimpses of King Allant's theme in Demon's Souls (I actually imagine this game like a distopic Sci-Fi fantasty Souls like). Amazing work
