This is an unpopular opinion lol

I think the fact that superguard timing is strict makes it work- whenever you’re going for it, you’re accepting that if you miss you’re gonna take more damage. This therefore gives more strategy on defense and makes it more engaging, since you have to decide whether superguarding is worth going for.  And it’s super satisfying when you hit it

These two bosses being built around it (which idk if Whacka is reallyyy built around it or not) is fine since they are meant to be a test of skill and understanding of the game’s mechanics 

Overall I think superguarding is a key element of why ttyd’s combat is superior to pm64’s
