Hi! Serious feedback here--Some of the attacks in the later "phases" when chara begins using the large screen breaking slash become totally impossible to no hit. An example of this is the sliding knives, Due to the small arena size and forceful timing, you are basically gauranteed to get hit by the slash, forcing a restart. This basically makes the entire later fight entirely luck based that you DONT get theese certain attacks. Theres really not much that can be realistically done about this issue without just disabling said slash during attacks like that.

To add onto this: I personally think that the no-hit achievement should be eased up a bit, seeing as a lot of the attacks are very RNG dependent and can be damn near impossible if not outright undoable depending on what controls you're using, maybe allowing up to 3 hits or disallowing healing items would work better to make the scene still a challenge to get but not unbearable.
Edit: Either one of those solutions or tweaking the attacks in general to all be purely devoid of random chance would work, it just depends on which part you'd prefer to keep I guess.
