Honestly, this easily and quickly became a favorite in my collection. There are a few quirky things but other than that, it's such a good game. What's really impressive is how detailed the game is. They really put so much thought and effort into it, it's amazing.
A few things: the Legalus menu. It's a bit too crowded to see things. Upgrading my Legions can be a hassle.
I wish there was a section to show you the completion of a level before you finish the level. For example, when i finish a level i always get the stats at the end and i find out that there were multiple sub cases that i didn't see or finish.
Other than that, perfectly awesome game and even though i'm not near to finishing this Astral Chain, i hope they come out with a second one.
