Hey, nice stuff! I love me a boss rush, and this delivers on that quite excellently along with some very goofy presentation and humor that reminds me very much of a @tombdude game. The concept of killing your opponents not by attacking them, but rather by demonstrating how ineffective their attacks are by styling through them to the point of embarrassing them to death is some really creative stuff: love how it promotes diving head-first into danger, similar to games like Doom or Burnout. Some of the bosses are a bit cheeseable here and there and it can be frustrating at times which can be bad since it promotes boring play, but for the most part I felt like they all had very interesting patterns to battle through and I had a blast.
In terms of feedback, there's the obvious one that the tutorial can be a bit confusing in that, while it does technically explain all you need to do, it is still nevertheless confusing and I wouldn't blame some people for dropping it thinking it's just a joke you can't pass (though I imagine I'm wasting my breath since that's probably a badge of honor for you, haha). Similarly there are some typos as well (some that even bizarrely auto-correct themselves as it goes) but I imagine those are intentional as they add to the humor. Other minor complaints are that I wish text and cutscenes and such would move forward at my own pace and be able to be skippable instead of just auto-playing. A larger complaint is that I do wish this game had a save/load feature: it can be a bit of a doozy and it'd be great to not have to do everything over if you run out of gas on the later harder bosses. Oh and it never saved my score despite me finally beating it!
Anyway, great stuff! I almost chopped my keyboard in half facing perfect circle man but eventually I got into the zone and it felt ecstatic to finally put him down. And if that isn't the ideal experience for a boss rush, I dunno what is, so kudos on that!
