Thank you for the feedback! Actually we plan to not having any healing items (since player had ressurect mechanic "Ascension") but we will tweak the game design with input from players also :D
The cave was boring since the levels unfinished (we try to update as fast as possible, but hold due during events) we will give new update so the cave have more interaction in the next update.
And we really glad you find the combat satisfying. We will provide more better update later. Thank you for the feedback once more!
