Only had a few small issues really. Some areas that were hidden didn't glow like the others, which made no sense (why should some glow while some don't?). Items on the map were harder to see than in Returns I felt. The map itself was detailed greatly, I just wish the doors that required certain powers were easier to see at a glance on the map. Also was looking for like 20 or so minutes to see what I missed in one area, and it turns out it was just an item that barely showed on the map. Otherwise though, the bosses all felt great, the new powers were cool, the level design was amazing, pretty much everything was as good as I feel it could've been. The last issue I'd add though is with the EMMIs. I really just wish they had another one or something. Towards the end I just felt they didn't have enough presence, at least when compared to the beginning. I at least wish the last one was a fight and not just killing it instantly in a cutscene.
