Twin Maniax! is a Ren'Py visual novel by Lemon Mint Soft, rendered with animated 3DCG. You play a confident young man whose promising life changes when he meets his girlfriend's twin sister, a notorious student at their school. The story frames his struggle between attraction and self-control as an erotic comedy, mixing school drama, political intrigue, and humorous situations. It explores themes of corruption, humor, and monster girl content.
The current build is v0.07, released February 14, 2024, and development is ongoing. It runs on Windows, Linux, and Mac in English, with no censorship. This update adds one additional full day, two new explicit scenes, five Gravure Gallery additions, and two eyecatch images. It also reduces file size through image compression, includes small dialogue and visual tweaks, and fixes minor bugs. The phone menu may still be unstable.
Developer's description
"Our young protagonist has it all: looks, intelligence, big plans for his future, and the drive to make them a reality. And more than that, he even got himself a beautiful girlfriend recently! But everything in his life will take a 180-degree turn once he gets to know his girlfriend's twin sister, the school's number 1 slut! How will he deal with the shock, and with the strange attraction he feels towards her...? Angel or devil, model student or bitch gyaru...? It's your choice! Political drama and hilarious hijinks alike are assured in this erotic comedy. Will this upright young man be able to remain pure among the sea of temptations he will face ...? Who are we kidding, of course he won't!"

Sadly this never got finished and there is simply not enough here of substance...the models and story aren't bad so to speak, there just is not enough of it along with content. Better to place your hope in something else.

2/5 is all I can give for [0.07], cause the visuals are actually well done and show some clear talent, and making your own soundtrack shows a belief in their project that I hope has them improve upon it. ----…
