Just finished the game and I liked it a lot! Got Ending A, and will try to get the remaining two. The soundtrack is rad and an interesting style choice for this type of game and the characters designs have a really good mix of creepy and cool.
Like some other comments mentioned, the UI is a bit too small and hard to read. I also find myself only changing between 2 or 3 of the available weapons and shields, and though most of them sound cool, they quickly become obsolete.
Regardless, this is a really fun and bizzare game; would marry an eldritch grease mass again.
