(Edit: this top part of the review written after playing the male side of the game)
In short, I think the game's alright, considering the price. There's nothing explicitly bad but it's not amazing either. Gameplay is basic - completed the male half in about an hour. Art is... eeh, as advertised. Sprites are better. Sound is functional. Minimal story.
More in depth:
Gameplay is quite basic. You only have the one plane of movement + a jump command. One basic attack, one "special" that does damage in a wide area (usually enough to kill trash enemies and floor a boss), and a jump which seems to do about the same damage as a punch around you. Enemies spawn infinitely and quite regularly, and don't have much in the way of attack patterns, from what I can tell. Once knocked down, you can use them as health pickups, or fuck them to regen your special bar.
I found myself able to easily get through the game by grinding basic enemies with the basic attack (and/or jump) until I had a decent number of heals saved up, fucking a girl if I got overwhelmed (enemies don't attack during this) and healing in that gap, then literally just jumping until I hit the end of the level and reached the boss fight. At the boss fights, just spam healing and punch/jump (depending on boss) and you'll beat them eventually. Some of the bosses do have unusual attacks but you don't seem to get the tools (e.g. dodge/block/ranged attacks) to beat them so idk what tactics you're supposed to use other than grind and cheese.
I found the button scheme kinda weird and only found the game playable because my keyboard has remappable keys that allowed me to fix that.
Art... well, like I said, is as advertised. I've seen worse but also way better. Personally find the sex sprites better (some weird stuff and interesting positions are there) but no fucking way are you expected to be able to cum to them mid-game, the speed by which they go by pretty much requires you to use the gallery. Kinda makes me question the point of them in the game - like I get how in a GOR-type game you might have to fight your own willpower to not lose, but here it's just window-dressing to appreciate later. The pause to fuck is useful as a gameplay mechanic but not all that erotic.
The story is... well, it exists, apparently. Some gang steals a guy's bag. You fuck them until they give it back, basically. Also weird shit happens. I'm not really sure why most of it happens. I think it might be parodying a story I don't recognise?
Sound is also basic. Not sure if the music is original or not but it's OK lo-fi (in the more literal sense, not the "lo-fi hip hop beats to study to" one) 8-bit-ish stuff. Sex has some basic slappy and cum sounds. No voice.
Honestly, I just don't want to seem like I'm ragging on this too hard. It's not an asset flip, nor is it trying to sell itself as some new epic or baiting a never-ending patreon. It's $3. It's alright. I'm not really into male MC games but when you're this detached it doesn't matter all that much.
EDIT: Part 2 - the Female part:
Basically the same, but with some tweaks. You can cheese the same way, but less effectively, because enemies drop random items with different effects. You also get knocked down and fucked after a few hits, slowing you down. If you're grabbed then you may as well use the break to heal up though. Only one kind of trash enemy, unfortunately, so you only get two animations for solo sex and two for three-ways, other than the bosses.
Bosses are kinda harder and easier. This time they fight alongside the trash mobs, so you always have a supply of health, but also have to manage those and the bosses.
The additional art from beating the game seems to include one scene from winning against a female enemy, and three from losing to the earlier bosses. You can't actually replay the cutscene from the extras screen, as far as I'm aware, just look at the CG. I'm not sure if the three boss loss scenes have an actual cutscene though - the trash mobs get to you before they do 90% of the time. I did manage to lose to the bunny girl's sex attack once, and that didn't trigger a scene, but I'm also not certain that I didn't miss or skip it somehow. Not too keen on testing further considering how tough that was, although the ending does imply there may be more of the game to come. If so - wouldn't mind a cutscene for those losses and/or a way to see the text again upon beating the game. Story matters!
Also this is kinda relevant to both parts but didn't mention before - I don't know what's going on in the background of most scenes, but it looks interesting.
