Thanks for trying the game out even though it's not your standard genre of choice! I really appreciate the time and effort!
I'm glad you recognized the gameplay loop and found it enjoyable, as well as the acknowledging the suspense when waiting for the attuning to finish, those were all deliberate choices and you've picked them all up!
By raising HP, are you referring to raising max HP or just restoring HP? Your maximum HP does increase with every Level Up, and there is the "First Aid" skill that acts as a clutch in emergency situations, as well as being able to carry up to two Blessings of Life.
I definitely wanted to showcase the gameplay and systems in the game, so the plot is understandably under-developed; I'll make sure she does a better job at convincing in the future. =)
Thanks again!
