Yes, it takes some getting used to. I wanted to make hits and misses entirely skill-based instead of RNG-based and it should still remain challenging further into the game. That's why I had originally decided to make it this fast.
But if I ever continue to work on this one, I would have to completely recreate the entire battle system in a newer version of GB Studio anyways. That would give me the chance to apply what I have learned since then to make the battle system feel more responsive, making the speed a little easier to handle.
