The real score would be 3.5, because I think this is slightly above average.
This game, or rather, this dev has great potential, despite there being obvious faults here.
(Spoilers)
Firstly, I can only really echo the other reviews here and give the disclaimer about the prologue: The game opens with a pretty long sequence of the MC getting "tortured" to set up the revenge-plot of the game. It is skippable by leaving the poker-game early, and mostly an unpleasant read if you're not into it.
After that there is another pretty long sequence that is mostly dry and worldbuild-y, and then the tone shifts completely into the best part of the game: sex-comedy about superhero-tropes.
I have to say, despite the medium being, in my opinion, kinda bad for comedy (hard to control the timing and setup of punchlines to tell good jokes) there is a lot of good, funny writing here, and the concept of a guy turning to supervillainy because of his small dick and failed masculinity is inherently funny, even if the game could have taken a more elegant, shorter and more funny path to it. Not to say I don't get that it's supposed to be relatable, and "justifiable".
I think the execution of the story-structure after the opening is kind of weak, with the gameplay being super barebones and storylines being just things you click off of a map. This is not the most elegant execution of this kind of concept, but it's what we have. You pretty much get dropped from the prologue into your lair, which is a jarring switchup.
The game also kind of lacks a connective tissue between "The origin story" and "taking down the heroine" in most scenarios. I think putting down more limits, like starting out with a selection of 3 heroes and branching out from there, would have contributed more to giving time to set up the characters slower, and give more time to limit progression from a no-name in a unitard to an actual threat. But I get that writing comedy is hard, there's a pressure to add content and prioritize sex-scenes, and it definitely was necessary to quickly make clear what the rest of the game was going to be, but still...
Speaking of content, the visuals are great. They might just be the most impressive part of the game, and do a good job being stimulating, and can carry most of the sex-scenes. But the scenes are mostly generic aside from the focus on NTR in the beginning, without really committing to any other theme besides the skin-tight, amazonian look of the women.
Overall, slightly better than average, and slightly more unique than most games. I am not a fan of pure VNs, so I would always like some more depth to gameplay, but you can't have everything.
