I quite like the sound effects you used for the game especially for the dialogue and footstep sounds. Also it's great to see another game that also uses CTB and pop up dialog windows. The taller rtp character assets that you used are very cute as well.
However, when it comes to the UI of the battle window, I wish that when you open the skill window, the actor names window is also hidden. Because now the skill names sometimes overlap with names of the player characters and that is a bit hard to look at. Also whenever I died, I had to watch the opening cutscene again instead of being able to immediately load a save which I would prefer.
Overall, I think the setting is quite interesting and is very cool that I get to play as a skeleton character.
