I actually don't like Vampire Survivor or other such games, but I enjoyed the music and pixel art of this one. :)
I beat it on my first try and I felt it was a bit easy. I just walked around in circles and gathered enough orcs in one place to cut them down all at once, which generated plenty of potions in one spot to heal me back up instantly.
I also felt the movement speed was a bit slow.
Controller support would be awesome with this sort of game. Maybe left stick is movement and right stick is direction (maybe with some kind of indicator, since you don't really see which way the character is facing). Then some button to attack.
