Hmmm, this was a bit of a bummer for me: I totally love the concept and think it's really cool and funny, but over time it just became so repetitive for me that I just let the hero kill me so it would end, haha. I wanted to see how the game naturally resolves, but didn't have the patience.
As said, initial impressions were strong. The concept was amusing alongside the dialogue, and I loved both controlling the sluggish boss and learning all of its secret moves. Presentation was solid as well, with tons of little touches like how the music builds up when you get damaged enough to represent new phases. I found it a bit confusing that the game's HUD was from the perspective of the player (their health bar in top left and boss in bottom middle) as well as the death message being "You died" instead of "They died", but I felt like that was part of the humor so I let it go with a smile. From there, I kept playing, wanting to see how the game would escalate and what the characters would talk about next.
But as time went on, I grew really bored with the game. For one, the AI for the hero was brain-dead, so brain-dead that I was curious whether it was so bad so as to stretch out the game so the hero wouldn't win too early and make you miss intended dialogue events. Whether this is or isn't the case, fighting the hero just felt bad, unchallenging and repetitive because of this, amplified by how sluggish we control. I know it's part of the experience at how the hero is so bad that all they can do is keep grinding to win by numbers, but at the end of the day, all this didn't make for a fun experience for me. Also, I found the dialogue hit-or-miss: some of it was quite amusing, but other times it would be a bit too fourth-wall-breaking and overly quirky with references to simping and such.
So, with both the gameplay being boring and the dialogue not worth it to keep going for, I let the hero kill me (and ironically, that was the hardest challenge since the hero is just that goddamn bad, which was probably the funniest part for me, so kudos for that?) Again, I really love the concept and feel it's a great and impressive game jam prototype: would love to see this polished up and executed better in a full version.
