Spoiler: Change-Log

v0.30
-Miku Cowgirl Mode: Access it in the sex menu. Cunny --> Go!(Alt)

-You can click the "Switch Position" button to toggle between cowgirl or standing missionary scenes.

-Light Adjustment: Adjust the various lighting settings for the scene! (Cowgirl only for now, while its tested out)

-Special Pupil Options: In the dressing room you can set special pupils for Miku! You can either toggle them on all the time, or uncheck the box to only have them flash during certain events. (Auto-Flash is only coded for Cowgirl atm, will expand upon later).

-UI Toggle: Press "U" to toggle the UI on and off.

Bug Fixes:
There was something minor, I forgot what it was though lol.

v0.25
New Changes:
Added Grope Mode!
Access Grope mode from the main hub. Allows the player to pull and tug on Miku’s juicy bits. Pressing “Tab” switches to a closeup mode for more head interactions.
If Grope mode kills your FPS, try enabling the “Low Quality” check box. This will cause slight cursor jitter but also boost FPS.
Revamped Supporter Unlock system. The game should be unlocked by default for supporters if downloaded from the following links.
Bug Fixes:
Fixed a few minor UI problems for widescreen users.

Not sure why, but this one was removed from F9.

 

[sharkz]

Well it's actually quite simple, they removed the Animations of Mantis as well and i bet it's the same exact reason why they removed this Game.

What would that be? Because Mantis-X's main content is loli?

Yes, the Collection was avail. (without lolis) before they began deleting "questionable" Games / Animations.

Ah, okay. Do you think I should keep this one here in +, or move to gen pop?

i see the tag for character customization. can you fully change miku? if not than i don't think it belongs here, unless there is a patch out there that does it.

I think you can change her hairstyle and tattoos.

 

[sharkz]

I don't understand why they deleted Mantis content in the first place, from what i can tell and from what i've seen they could have kept it as it wasn't against their Rule, like at all. It should be save to change but better be save than sorry and may ask other Staff.

"Abundance of caution," probably. Mantis-X is pretty well known for loli content, and they're probably worried that there's some secret way to lolify Miku in there. I doubt it.

As it is, the game should not have been banned, and equally should not be here in games+, but just as equally this section is explicitly for games that were banned there, so I guess it sort of "should" stay, after all? IDK, up to the mods.

I personally think "we" should be doing our own thing and deciding for ourselves what belongs in games+, but that's easy for me to say with the grandfathered-in Plus account, and selfish reasons - I just want it to be easier for myself to find loli content. There's a bunch of stuff with obvious loli (and incest) content that really should have been banned on F9 according to their rules, but never was. That means those games stay in gen-pop, and there's way more shit to wade through there, looking for diamonds. Yes, I know there's tags, but user-created tags are unreliable in all directions - sometimes a game with ZERO loli content gets tagged, and sometimes games with loli content are missing the tag. (And then like this game a bunch are missing censored tags... at least if the screens are anything to go by, this is censored - not willing to find out myself for a non-loli game, even if it is Mantis).

I agree that we should be preemptively moving games to games+. There were quite a few I found and added recently that had been on F9 at some point, but there's no telling when it was removed.

Also, yes this is the uncensored backer version of the game. I'll update the title to reflect it.

Im fucking Miku Miku oo ee oo

 

[MisterRoboto]

MANTIS X MADE A GAME?????

Three, I believe. But two of them have been abandoned, it seems. Regardless, they are coming soon.

 

[warhendy]

[falafal]

FYI, the gofile link is coming up as empty.

Let me look into it. I may have missed a patch somewhere.

Apparently I misinterpreted the post the game came from. The backer version is also censored.

Weird, considering that matnis animations are never censored.

This is news to me. Albeit I wish we could turn miku into a loli instead of just reduce her tit size.

Also the game performance is weird? Either potato or high graphics options gives me the same FPS.

Apparently there was a change a while ago where fanbox disallowed creators from sharing uncensored links, even to backers.
