I like to review H games, by ignoring the H and looking at the game itself and see if its a good game overall:
Pros:
-Banging soundtrack
-addicting gameplay
-Angel boss gimmick is super unique and makes good use of the H game premise
-Fun character designs (the sprites you dimwit)
-Great alt costume designs

Cons:
-A bit on the shorter side
-game kinda just ends abruptly. like you get access to the last area and going through that area is super fast.
-the costumes for the boy (while well designed) are kinda bland, like a little bit of "spice" would be nice
-for you 100 percenters, the coins you have to collect are completely hidden behind false walls and there is no item to help find them

7.5/10 - Great game

Great art, music, and gameplay!! 10/10 would recommend

Obvious hentai aspects aside, this game is a genuinely fun experience. Most 18+ games tend to be pretty boring game play-wise but this is a solidly fun platform/metroid game with really engaging mechanics. The gacha ball and outfit collection aspect is great, and I like that you can view the gallery of said collectibles after the fact.

The art is SUPER cute and really well animated. A lot of NSFW games tend to be weirdly visually ugly for some reason but the pixel art is adorable and fun to look at. Sad there isn't any M/M content but still a fun experience!
