I'm still playing through the game but I think the mechanics are mostly good. It took a little while to get the hang of it and it seemed hard to judge the damage I could expect to do but I think that's maybe something I'll reconsider when I play again.
Some of the colours of the buttons were a bit hard to see, like when I was in a menu to attack or choose an item I didn't notice the return button sometimes which is maybe something to consider.
The overall battle system was good in my opinion. Well done.
