The humor is 11/10. Unfortunately, I can only judge much of the content loosely based on watching Padr's playthrough (which was a lot of fun to watch to be fair) as I was just not able to deal with the input system in any capacity.
You're supposed to match the rhythm of the inputs but the "check" for holding the input occurs so late that it's sometimes not always even possible to switch direction buttons quickly enough to meet the next check unless you're on a keyboard. I'm aware of the exploit to just hold multiple directions but I don't really like playing games to not engage with their systems, if that makes sense. (I also prefer to use a controller when supported)
And the lack of warning before the enemy timer makes it nearly impossible to parse their patterns before it checks for the first input and fails you. You might be able to fake it by holding down a random direction when they queue an attack, which fortunately the enemies seem to go second most of the time, but all told I would've just rather had a MGS parody flavored DQ clone. EDIT: one alternative suggestion for making the "CQC" less punishing would be to make it more like the Mario RPG / Mario and Luigi series where you get a bonus for landing the input, but the skill does something if you miss.
Art, music, vibe, and writing, all very good.
