Super cool game! Took me a minute to understand how to sling spells but I eventually figured it out and the game instantly clicked. Felt satisfied using the really strong spells. I think I only really have a couple of critiques to give:
1) I didn't really spend a lot of time looking at the enemies or the characters traveling the environment. Solely just looked at the spell-creating tables since I had to prepare more powerful spells as I marched towards each enemy. Is there a purpose to look up at the specific enemy you're going to encounter? Maybe if you had more enemies per combat encounter, and the choice to apply certain spells to certain enemies, that part of the screen might get visually used more and have more of a purpose.
2) Additionally, the spells kind of appeared to do the same thing (other than the heal). Wasn't entirely sure if they were supposed to be more effective against certain enemies, or if they had any impact on gameplay (other than damage). Would've been cool to see how different spells change the gameplay. Like if a powerful fireball was cast at the highest potential, would it burn the environment and make the next combat encounter easier? Stuff like that would be cool to see if you keep working on it.
Good stuff anyway!
