Loved the art of the game! The controls were probably the weakest point. I also got stuck in a wall and I lost the shield and wasn't able to pick it up because it went off screen.
As it's been mentioned before; one button to pick up a weapon would be a lot more intuitive. The movement seemed really sluggish, that may have been the point but it just made it a chore to grab weapons if they got too far apart from each other. I also have no idea what the sword did since every time I tried to use it it only worked once (I was probably using it wrong but I have no way of knowing that)
I really liked this take on only having one weapon though! It definitely would be fun to play with a more tight control system and refined gameplay loop. Well done overall!
