I'm glad you liked the game! Sorry for the late response, it's been a hurdle answering things on different sites while fixing things. I think the new accessory system got a lot of potential, but yeah, I agree it's not fleshed out yet. I got some ideas for Black Kalev for sure. As for how prominent role he'll have remains to be seen...
Levi is kinda one trick pony, true. With his skills only affecting on-field combat. I'll still be shuffling skills around with different characters, so I don't know yet how he'll turn out to be in the end,
