Cool graphics! I love the top down 3d look. It has potential. Shame about what happened with your original 3d artist.
The melee combat was weird so I avoided it by sprinting past everyone. It was very difficult to do damage without taking the same or more damage in return. Need a way to mitigate or avoid damage such as giving the player more range or a dash with damage ability.
The sun component was cool but I wasn't really sure why it was there and how it fit the theme of the dungeon.
Good effort though!
