Really unique entry (again!) - Like another commenter mentioned, a turn based bullet-hell is not what I would expect, but it works well.
The telegraphing works really well and it probably the strongest part of the game for me from a design standpoint. The only telegraph that didn't fully click for me was Crownelius, I couldn't quite work out which rings to stand in as I seemed to be losing health from one of them, maybe I needed to be in the larger but not the smaller?
Regardless it's a great game, and a very interesting take on the theme.
