I downloaded this one in Japanese a while back, and played through with machine translation. Game is somehow less than the sum of its parts. Art is competent, but the story and combat systems are kind of lacking. Nearly all the combat cards revolve around getting elemental stacks, but it takes so long to charge the skills that give the stacks it's just not worth it.
Can I just go stragiht to the mosnter fucking or do I have to deal with the self-insert MC first? Also, how do I get the goddess scenes? Thse seems to be the only decent scenes but seems like I'd have to play the entire game first AND know what to do to trigger them.
The succubus explains how to trigger the scenes for you. The gameplay loop is:
Head north and battle your way through the levels, to collect the currency, free imprisoned girls, and free a main girl after each boss.
Return to the village at night time. Head to the altar on the left to accommodate the freed basic girls in the village (if you've built enough houses). Now head to the statue in the centre of the village and use the fascination thing to make everyone horny. Now visit a main girl's house and use the potion thingy to get a sex scene with her and progress her corruption. Then visit the goddess on the right of the village and use the spiky things to sacrifice the basic villagers you have, and get the help of the main girl you corrupted this night, to get an animated scene with the goddess. This gives you some experience and levels up cards relating to the basic villagers you sacrificed.
You can use the eye in a circle thing to buy stuff, and as you corrupt the main girls you unlock their weapons to use. The game feels really unfinished, though; there's no real ending (after beating all the bosses you can also get an elephant demon scene with the goddess when you visit her at night, but it has no preview image), you can't talk to most of the girls in the village, the card upgrade system is practically pointless, etc.
There's also a fun infinite money glitch, which makes all the level grinding pointless. (I don't know if that's fixed in the version here? I might have played an earlier version?) The way I was able to do it - you're supposed to be able to disenchant basic weapons for currency, but not the girl's special weapons. However, the game has this programmed backwards. If you have a basic weapon equipped, you are able to disenchant a special weapon on the ground, and if you have a special weapon equipped, you can't disenchant a basic weapon on the ground. But the special weapons always respawn on their plinths in the village. So:
1. Head out into the levels. Find a basic weapon, equip it, and take a warp back to the village.
2. Pick up each unlocked special weapon from their plinth and swap with the basic weapon to leave you holding the basic one and all the special ones on the ground, then disenchant all of them.
3. Walk into your house and back out to respawn the special weapons.
4. Repeat as often as you like.
For some reason this doesn't work the first time you load the game, I needed to go into the levels and warp back to get it to start working. But with infinite currency you can buy out the shop every day and trivialise everything else.
