Nice! I'm one of the few people who, after an hour of vampire survivors, said 'meh', but I really enjoyed this. I think I like the faster pace of movement - it feels like you have more agency.
I found the pistol and katana quite hard to use. I might have preferred higher usability but with the same chit ratio (the whip in VS is a really solid weapon, vs the starter katana here being quite difficult). Really liked this, obviously.
I'm colorblind, and I had a little trouble with the darker enemies against the background. Not sure how to address that one within pico8's boundaries.
