I really want to like this game, because it does almost everything right, but the boss fight is unbearable. I think I know how to hit her during the multi-directional laser attack without taking damage, but the conditions for this to be possible (Patchy moving towards the wall I'm wall-jumping off) are rare, and the following attack is more of the same. It doesn't help that the first attack is also a "patience check" where the player is basically waiting for the boss to present an opening.
I guess the game does a good job of conveying the frustration of not being able to fly, but it's just not fun to play.
