A small update, I improved and expanded the effect animations in the game, now they appear for attacks (divided between slash attacks, hit attacks and fire/explosions), power up and down, and healing.
Maybe I'll add more and I'll also tweaks here and there, but I'm happy with the result, they're adding more life to the game.
The game balance is now closer to where I'd like it to be. Fights don't feel impossible but you have to work harder than before, especially with normal encounters.
