For me, this is the BEST 2D PIXEL GAME in this jam so far (the best 3D is ours XD), and I really like the way you interpret the theme lol.
I love the background story! It makes me imagine this lil game being expanded into a bigger RPG someday.
While playing, I spent some time memorizing which eye against which enemy. I was wondering if the connection between the eyes and the enemies could be stronger, e.g., if the Blood Magic Eye uses Vézias's own magic blood, it does make sense that the Mage who also uses magiccan resist it. In this case, I think the Knight would resist the Knife and Heavy Magic Eyes, etc.
The colors between eyes and enemies (match or not) also affect me. I mean the Mages and Rogues are easier because the eyes that they resist have similar colors, so I can quickly make a decision.
Hope my feedback helps ^^
