Thank you very much for the feedback! I appreciate you sharing your thoughts on this.
I'll see what I can do in making Lunelle, and other characters for that matter, more relevant strategically to incentivize trying them out. In the meantime, Lunelle has the highest magic stat in the demo. Her water Aura Skill works really well against beast type monsters and the Resistance debuff increases your damage output even more. Hopefully, when the game is completed people can customize characters' skillsets even more to further suit their needs. Thanks!
