It feels quite janky, it's hard to tell if the knight is responding to what you're doing, it could possibly be helped with switching the weapon as soon as you do, instead of when he's ready to attack.
It was also unclear to me that all of the skeletons were going to attack, whereas I thought it was just the front-most monster.
Furthermore, I thought the potion was a one-time use item, so I was quite confused when the hero kept chugging all the potions whilst having their weapon out.
The idea is nice, and it's a fun twist on the turn-based combat genre. The art also fits the game well, I particularly liked that the main menu was a book, considering the title.
