This was a fun survivors-like, going first person was an interesting choice
I thought the UI was really good, maybe could just flash a description of card abilities when they activate to help learn what they do
i found it a bit hard to see if you're bumping into enemies behind you even with the mini-map(kinda just went off of the getting hit sound effect)
since this type of game focus on progressing your dps, hp bars/damage numbers for enemies might be a good addition
the art and music is great
