It's gotten really robust! I do think a symbol guide might be helpful at this point, and other than that...? Achievements? Score tracking? The game balance is pretty good. My death was a bit cheap here (One enemy took all 21 of my armor and the next just murdered me outright from full health) but might have been avoidable if I could remember the enemy skills better or how weapons swap/stack better. And you can guess from my gold I hadn't seen a shop in a bit.
One suggestion: when the player has only one weapon, the next weapon picked up should go in the empty slot, rather than replacing the equipped weapon. I always forget to switch to my empty slot!
