This is a good start. I played twice. The first time I explored the tides and reached a soft lock where no choices seemed to let me advance. The second time I followed the amulet and was able to play through to the end, choosing the self-sacrifice option.
The main thing I noticed is that there were a lot of buttons that seemed to do nothing.
The relics changed the text in the top section to include "Examining" and the name of the item, but I did not see anything else happen.
Some of the options in the story area seemed to raise stats in the Soul of the Heir section, but otherwise did not do anything, such as showing flavor text about what happened. It would be nice if there was some story/flavor text, or even just a popup mentioning what happened, or other indicator by the stats that changed, such as a glow effect, to draw the eye. I did not notice them changing early on as I was figuring things out and just had that flicker of something in the area, but not certain if anything changed, and if so, what.
Similarly, it would be nice if any buttons that did nothing, including those you had clicked and are no longer useful, were disabled or greyed out. I think some of the buttons that seemed to do nothing may have been from stats that were already maxed, or at minimum. I did noticed that if a button raised stats I could just keep clicking it to max the stat, and then it did nothing when clicked.
