No Crisis Flash(aka the red flash that indicates enemy attacks) really screws me over, you just hafta feel out the attacks. Though its nice you highlight the projectiles, it's just that I wish there was a way to distinguish between projectiles that hit you and the projectiles that will miss you. The Time Crisis games usually highlight slow-moving(non-hitscan) projectiles with an Orange tracer on top of them being able to shot mid-air.
Defeated Sakuya in the third attempt. (my spam-clicking too stronk lol)
Accessing the options menu from in-game doesn't work, I can't click on any of the options. But other than that the game runs smoothly.
