It looks like there's a lot of art assets that'll need to be done, so I completely understand only being able to manage roughs for now- but I think it still does a great job of giving an idea of what everything is going to look like! Battles seem really difficult to balance though, I've been hesitant to dip my toes into it properly because of that, so I don't envy you. But again, I think you've gotten a really good start, in terms of forcing the player to be smart and not just brute force their way through! So I'm sure that you'll be able to figure out balancing with trial and error ^^/
I believe in you!! And I look forward to seeing it progress!
