On its own, I think this game is too simple for an RPG, with it being entirely linear. However, I know that it is part of a series. I think most of the changes between this and the alpha version (the first in this series) are good. I much prefer the menu design, overall UI, and I think not having as much max HP early on is good. However, it seems like you've kept the old amounts that they heal, which means that there are multiple things that just increase your HP to max.
Also, a big problem i've noticed in both this, and the alpha, is that the timing for the music things is weird. I can rarely seem to get it to work, and its unclear when exactly you are supposed to press the buttons. If this isn't fixed, I probably won't play as Eli.
With Jolyne, on her spark timings, it feels like when the bar stops is slightly after when you press it, which can be annoying.
Also, I found with Jolyne, just using spark is enough, I barely used the normal attack. I think the normal attack could give more MP when done perfectly, making it more useful.
