I guess it's mostly up to me usually playing RPG Maker games by mouse not keyboard. In the beginning I found it hard to understand to which place / base to go next and sometimes I seem to be able to use a defeated character again (there probably is a reason, but I didn't see it, so it could as well be a bug). There's also no real fighting screen in the first round, which may be a bit confusing, but I don't think it's bad since it makes the fights feel more varied.
