Great game! The concept of resurrecting fallen comrades and fighting together with them is excellent. The art, sounds, music are good as well.
Attacking felt kinda weird and slow sometimes and most of the time I couldn't attack an enemy without taking a hit myself. Also, In the last part of third level, I was able to run away from enemies and reach the chest without defeating the enemies so you might want to lock the path until all enemies have been defeated.
Great work overall!! :)
