I agree more Visuals and Sounds would go a long way.
We had planned to get those in, but the Main System Mechanics, Models, and Animation took longer than expected. And honestly I kind of forgot about getting Sounds in lol.
A defensive dash could be something to consider, but I think it may be too much/too strong. If this game is worked on more, it might be a question on balancing defensive options more than adding new ones.
