Movement is good, and the directional attacks are a nice touch. One thing I'm worried about is if I can just spam the arrow keys all the time and attack constantly, it can make tuning the difficulty quite difficult. Attacks should have some time when the character is vulnerable - like if you take a swing with a big, heavy axe, you need time to recover during which you're vulnerable. Risk vs reward!
I picked up the stuff, and opened the inventory, but I'm running the game on an ultrawide screen, and the bottom of the inventory was cut off, and it was unclear how I should interact with it. While 5160x1440 is an unusual resolution to run at, people will have all sorts of hardware configurations you'll need to make sure work!
Neat concept!
