The default keyboard control for the game is kinda uncommon. You would need to use Q W A S Z X. I would recommend to use controller for this game or remap the keyboard in game for better experience.

And the combat of the game is also not what I was expecting: There is a strategy to equipping proper items, but the combat itself is more like a button smasher type.

Update 1 (after playing additional 6 hrs):
Combat is okay, if you have equipped the correct items, it would make the combat much easier. Enemy can heal themselves if you weapon damage element match their elements. I made a mistake equipping all my weapons with the same element and one fight took forever to complete.

I gave up on following the story. Like the difficulty setting mentioned, it is told in a visual novel style. You need to spam your buttons and read through the dialogues, which is not my type of game. I do like some of their dialogues, but the overall delivery through visual novel style killing the game for me. Be warned, if you do not like visual novel games.

The sound effects and in game music got annoying really fast, I muted them and set up my own music while playing.

Maybe I will finish the storyline one day.
