I finished it today and admittedly I loved it all but the ending. I get you wanted to show the darkness of it all, but it felt.. off. I can't think of any other way to describe it.
Another way it coulda gone, after a battle, the player has two choices. Kill him, or walk away( and then you could still do the ' kill the player bit' by havingl Ike Darkrai appear and murk em)
Either way it ends in a dark death tbh. Cause lbr
Dreary probably woulda had some back up people to do his work like that scientist.
But overall I enjoyed the darkenss and the mystery and wait for another
