For the record, I just jumped into an abandoned station where I'm already wandering around the environment looking for enemies to fight...and I did. Slowly.
First off, you have all your attacks laid out before you in these little rectangular buttons, which you can select by pressing left and right on the d-pad. Once you select one, you can attack an enemy. I don't know if it was just me, but attacks felt like they had a 1-2 second delay before executing. To add to the waiting time, after every attack you must wait for the circular guage to refill again before issuing another delayed attack.
In any case, battles have now become more sluggish than it needs to be. I had to idle my time running around in place, just to wait until my meter's full before getting my attack in. While this might be fine for people that have the time, I certainly don't.
I'm sorry, Level 5, but if the gameplay doesn't capture my attention, then it's not meant to be.
