This is really good and I wish there were more enemies so I could play for longer!
I found the different types of relics and items really unique and they all had really good sprites, I did encounter a bug where items would overlap on top of eachother (or keep the sprite visible in an empty slot) in the windows build but it never fully harmed my experience. I also think the ability to stack health bags would've been nice as sometimes the game wouldn't count them together as a pool of health (eg 10 & 7 = 10), but I think I did see some effects were designed on them not being stackable so that's just a me issue!
Generally I really liked the fast paced music and clean artwork, I really hope you will do more with this in the future!! Great Job!
