The game is very good, I believe it has the potential to be one of the best on the site, the girls look a bit similar but that's not necessarily a bad thing. At first, the story universe seemed very similar to Eternum, but the issue of superpowers and "vigilantes" distinguished it quite a bit.
The protagonist is not boring, but also not very interesting, I believe this is the worst case scenario for a protagonist. Some people like a character without any personality and a game full of choices, and some people like a "complete" character and a linear story; as I noticed that the DEV values quality, I would recommend that he goes down the path of choices and different routes, which is much more complicated, but with the quality that I saw from the DEV, it might be possible.
Regarding the art, it is very good both in quality and art direction. Some close-ups are very well done, even in the sex scenes. The problem is the lighting, it often gets a bit dark or with low contrast. Fixing this, the art will be in the category of one of the best in this type of game.
Overall, it is a project with a lot of potential, I hope you continue with the development and more people get to play it.
