I've reviewed a fair few Dieselmine H-games over the years, most prominently the Violated Hero series. They were always light on gameplay and usually pretty good on art. Nowadays they seem to be in a really weird place. They probably have one of the most gifted smut artists/animators around, L Buffer, working for them, but don't really seem to know what to do with him.
Unlike its predecessor, A Lose Hero in the Castle of the Succubi, which was pretty much a glorified gallery where you walked from H-scene to H-scene, Mage Kanade's Futanari Dungeon Quest is technically a game, just about. You have an attack button, a dodge button, and have to navigate fights and timed puzzles.
I'm not into futa, so originally didn't have much interest in this. Then I saw some clips floating around on porn sites and was lured in. What can I say, I have a weakness for sexy squishy slime girls.
|They got me. They knew my weakness...
The one area I'm sort of okay with futa is futa protagonists having their 'weak point' targeted by sexy (and importantly, non-futa) succubi and monster girls. And in this, the protagonist is pretty much functionally a dude with how the various monster girls treat them. I suspect the only reason they made the protagonist a futa is to double up on the ryona audience by showing a sexy chick with big tits getting slimed.
That's one of the features of the game. There is a large panel on the right that shows the negative statuses currently affecting the protagonist.
I played this untranslated, so I'm not 100% on the plot. A sexy female wizard chases a succubus to some ruins. After entering she gets tricked and hit by some magic that gives her a cock. Then she has to navigate her way past various erotic traps and monster girls that are bent on wanking her into a stupor.
|Not the boooooobs!
The game is quite inventive on that, to be fair. The first level has you trying to avoid gas and boob traps while fighting off disembodied wank hands and paizuri tits. The second is full of lascivious slime. The game gets across the theme of an erotic trap dungeon fairly well and the boss fights are pretty good. By the 4th level it starts to become obvious the devs are running out of steam. The traps and timed puzzles go away and are replaced with lazy battles versus hordes of horny bunny girls. The 5th is a replay of the boss fights, but with the 'lead' succubus of the level involved directly.
As with a lot of Dieselmine games, there is a lack of ambition. The early levels and boss fights are pretty good, but it's very short and feels more like a demo or proof of concept.
Art is variable. The L Buffer animations are excellent as always. I was less impressed with Bad End H-scenes. The art on those was a little too cartoony and the proportions on some of the succubi ended up looking weirdly grotesque rather than sexy.
|Sorry luv, you're just not my type.
As with most of the recent Dieselmine succubus and monster girl games, it's pretty much a showcase gallery for L Buffer's talents. Those are good as always, but the whole thing is probably a little on the pricy side for what you get. It's a shame Dieselmine can't seem to put those talents to better use. Other devs would salivate at the prospect of having this sprite work in their games.
(If I could get a artist/animator as good as this to provide some graphics for The House of Hellish Harlots...)
The erotic traps are interesting, at least for the early levels. I'm currently brainstorming a SexDungeon project for #Dungeon23 over on Patreon (and SubscribeStar). This has given me a few ideas for things to work in, like the Boob "Wall of Death". Mage Kanade's Futanari Dungeon Quest is maybe a little expensive for what it is, but it's fun and given me a few ideas, so checking it out was not a complete waste.
|Beware the "Wall of Boob"...
Milking Farm is probably still the peak of the L Buffer/Dieselmine era, even if that also only had rudimentary run 'n' hide gameplay.
